Pinkie woke up the next morning, stretching her hoofs up and yawning so widely her mouth felt like it was stretched over most of her face. She looked around her room above Sugarcube Corner sleepily, then scratched herself with a hind leg like a dog. Pinkie looked out her window and saw the sun still pretty low in the sky, meaning it was still early in the morning. She suddenly gasped and grabbed her pet alligator Gummy on her bed and swung him around.
"Gummy! Guess what today is!!" Gummy looked back at her with unblinking purple eyes. Pinkie giggled. "No, silly, it's not random holiday day! It's later! Do you know what that means?" She didn't wait for Gummy to "answer", "Dashie and I will finally do some pranks together! It's been SOOO long!!" Pinkie set Gummy back down on her bed and kissed him lightly on his head. Then she hopped excitedly out of her room and out of Sugarcube Corner, not paying any attention on anypony around, just her fun-filled day before her. Pinkie suddenly saw Rainbow Dash out with Cloudchaser, a pegasus with a purple coat and a spiky white mane, and they were giggling together by an outside table, stealing glances up at Pinkie. Pinkie stopped before Rainbow Dash, confused.
"Hey, Dashie, it's later! Are you ready to do some more pranking today? Huh huh huh?!" With a big smile on her face, she got closer to Ranbow's face. With a disgusted look, Rainbow Dash pushed Pinkie away roughly. 
"What are you talking about? I'm just hanging with my cool friend here, Cloudchaser." She put her hoof around Cloudchaser's neck and smirked at Pinkie. Cloudchaser did the same, and said:
"So buzz off, weirdo." Rainbow and Cloudchaser high-hoofed each other and stared at Pinkie. She put her ears flat against her head and slowly backed away.
"Oh, that's ok, I guess! Everypony can have new friends. Have fun, you two! Wait," Pinkie suddenly perked up again, "What ARE you ponies doing any- Aaahh!" A shadow came over her head. A heavy downpour came down and soaked Pinkie to the bone. Pinkie looked up, surprised, at Rainbow Dash on top of a raincloud laughing hysterically.  Cloudchaser was looking at her and laughing as Rainbow Dash flew from the top of the cloud down to where Cloudchaser was sitting. All around her, Pinkie could hear ponies laughing at her as she stood there, her mane in wet strands around her face. Pinkie looked up at Rainbow despairingly.
"Dashie, what was that for? Did I do something wrong?" Rainbow Dash just looked at her, smirking.
"What's wrong Pinkie? I thought pranks were harmless?," her face got serious, "And don't call me that." Rainbow Dash walked closer to Pinkie as Pinkie shrank beneath her glare. "You got that?" As an answer, Pinkie just ran away, not knowing where to go, the laughs echoing in her ears. She finally slowed down near a lake and looked at her reflection, a wet, sad, miserable, version of her normal self. She thought to herself, Why would Dashie do such a thing? She wouldn't do that on purpose, I know that. But what if there was a reason for it? Maybe... maybe this is all my fault. Dashie didn't want to put up with my annoying tactics anymore. I WAS kind of in her face yesterday, when she was trying to hang out with the CMC. Maybe... Just then, there was a ripple in the water, and Pinkie was surprised to learn that it was a tear. She shook her head vigorously, trying to clear her head. She noticed her mane was still straight from the rain. That wasn't supposed to happen. Pinkie ran her hoofs through it, finally getting it to some representation of its former messy glory. Looking up, she saw the CMC with another young filly. Hmm, maybe I should go apologize to them for yesterday... Plastering on a big smile on her face, Pinkie bounced over to where they were. She saw them talking to the other filly, who, after a close inspection, she found out it was Diamond Tiara, whom she had thrown that cutesenera party for. Looking closer, she heard what was being said between them and her eyes opened wide in shock.
"Why did you take away MY tiara? You KNOW you shouldn't take what's not yours! That wasn't very nice, was it? Oh well, I guess you'll have to be punished!" Sweetie Bell, of all ponies, was in Diamond Tiara's face, levitating the tiara Diamond Tiara usually wears, and twirling it around in the air. Applebloom and Scootaloo were in a circle around Diamond Tiara, glaring at her, making sure she doesn't get out. The once so confident filly shrank back, closing her eyes and whispered:
"But-but Sweetie Bell... that tiara is supposed to be mine..." She curled up, not wanting to see her face. But Sweetie merely smiled and put on the tiara. She giggled.
"Oh, is it? Well, it's mine now." Sweetie Bell made eye contact with first Applebloom, then Scootaloo, and they slowly closed in on Diamond Tiara, shielding her from Pinkie's view from the sidelines. Pinkie got over her shock just enough to run over there, and shout:
"Hey! What are you girls doing? Leave her alone!" They all looked up in shock, and, only seeing Pinkie Pie, just stopped and smirked at each other, then at Pinkie. She skidded to a stop in front of them, and taking a short break to catch her breath, glared at the three of them the best she could.
"What are you fillies doing? Can't you SEE that she's hurt and sad? Why are you doing this??" Even she was surprised with the harshness in her voice. She had NEVER talked to ANYPONY like that before. 
"Oh, we're soo sorry that we bothered you, Pinkie Pie. We were just messing around with our friend here. Surely even YOU get friendly teasing." Sweetie Bell said with a pathetic looking pout on her face, sure that Pinkie would just bounce away with a carefree 'Okie dokie lokie!' But she couldn't be so wrong. Instead, Pinkie Pie held out her hoof to the still trembling pony inside the circle.
"C'mon! I know how to make you smile!" Diamond Tiara slowly removed the hoof over her face and looked up at Pinkie with shock. She was wearing a broad grin and was eagerly holding her hoof out, hoping with all her might that the scared little filly would come with her. She smiled shakily and grabbed the hoof. Pinkie smiled and pulled her up, then the filly followed her as she bounced away happily, with the CMC scowling after them.
Pinkie Pie took Diamond Tiara straight to Sugercube Corner, confident that, throughout all the strange things happening today, her adopted home would never change. Without her noticing, Pinkie's hair had gone straight again, meaning that she wasn;t as happy as she claimed to be on the outside. Truth was, Pinkie was only doing this to make the filly feel better. It did nothing to soothe her cracked heart over Rainbow Dash's behavior. And the former Cutie Mark Crusaders! She thought they were friends with Diamond Tiara now that she was nice to them, and helped them get their cutie marks. When they got to the sweet shop, Pinkie led her through the back kitchen door, where she made all her yummy treats for all of Ponyville to enjoy.
"Come on! It's CUPCAKE TIME!" She laughed halfheartedly and started to grab the ingredients for a batch of delicious cupcakes. She only hoped they would go out better than when she taught Applebloom how to make them, back before the CMC got created. When she looked back at Diamond Tiara, she was staring at her, a confused look on her face.
"Why are we making cupcakes?" But Pinkie only giggled and patter her head lightly.
"Because, silly, it ALWAYS gets ponies to cheer up after having a no good, very bad day!" She went back to all the cupcake ingredients laid out on the counter, and poured some flour into a big mixing bowl, making a powdery mess all over the kitchen, and getting both of the ponies all white. Pinkie snorted and fell on the ground laughing. After a while, Diamond Tiara joined her on the ground, laughing and snorting with her. Wow, Pinkie thought. She would NEVER laugh like that in front of another pony before. Maybe I did do something good today... Smiling, Pinkie got up, and helping the still white filly up, got to work making the cupcakes. Pinkie was sure that tomorrow would be a better day. As they were working, Diamond Tiara noticed that Pinkie's once lifeless mane had inflated a little bit after having fun and laughing.
