The next day, Twilight was just about to enter the school building. It was strangely quiet, but she had double-checked and it was, indeed, a school day. She entered the dark school building rather hesitantly. "Hello?" She called out.
"SURPRISE!" Yelled Pinkie Pie, as streamers shot out from everywhere and ponies cheered.
Twilight back-pedaled, before falling to her haunches with her mouth wide open. "Wh..whu...huh?!" She gasped.
"Why, it's a party, silly! Do you like it? Huh? Huh? Do you?!" Pinkie Pie yelled.
"Wh..what's a party?" Twilight said, absolutely flabbergasted. Pinkie Pie gasped before yelling so loud that it literally shook the school, "YOU DON'T KNOW WHAT A PARTY IS?!"
"Uh..no."
"Omigosh then I have so much to show you because parties are soo much fun and there's cake and balloons and streamers and games and punch and did I say cake and tons of ponies and ---"
"Um...class?" Light said as she stepped into the schoolroom, which was now in full-blown party mode, with some of the ponies even doing a conga line. The room fell silent as they saw her, then suddenly everypony was everywhere, trying to shove streamers under desks and gulp down the last bit of chocolate cake before it was taken.
"Uh...I can explain..." Pinkie Pie said, looking guilty.
"Look, I really don't mean to be harsh, but did all of you really think throwing a party in my classroom was a good idea? You got a mess everywhere, none of you will be able to concentrate all day, and I certainly will have to have a talk with all of your parents!" Light seethed.
All of the fillies and colts suddenly grew even quieter, thinking of the lecture their parents were sure to give them. Nopony noticed that Pinkie Pie's hair had suddenly gone flat, and tears had sprung to her eyes.
"Now, I'll need everypony to pitch in and help clea..." Light began, before being interrupted by a series of loud sobs coming from Pinkie Pie, who by this point was streaming tears.
"I didn't mean to make such a mess and now everypony will hate me and nopony will want to come to my parties ever again and all I wanted to do was make Twilight haaappyy!" Pinkie Pie sobbed brokenly, before running outside of the classroom.
"Uh...I'll go get her, miss Light." Twilight said.
"Yes, please do. I really am sorry now for having lectured all of you like that, apparently Pinkie Pie took it really harshly." Light sighed.
Twilight went outside the school, and after a few minutes of searching, she found Pinkie Pie crying behind a tree. Twilight slowly trotted up to her."Are you alright?" She asked.
"N..no. All I wanted was a party and fun and now I've ruined it for everypony and you didn't even get your "Welcome To Town" party!" She cried.
"Pinkie, I'm not new to town. I've lived here all my life, I just don't get out much, so that's why you haven't seen me before. And you didn't ruin it for anypony! We had fun while the party lasted, even if it was only for about two minutes, and even if we are going to get lectured, that doesn't mean anypony is going to stop being your friend!" Twilight smiled encouragingly at Pinkie.
"Y..you really think so?" Pinkie Pie said, almost in a whisper.
"I know so!" Twilight hugged Pinkie Pie, and Pinkie hugged back, saying, "You know, Twily, you're a great filly. Thanks so much for cheering me up!" Pinkie let go and wiped her eyes with the back of her hooves as her hair poofed up again. "Does this mean we're friends?"
"Of course, Pinkie." Twilight grinned.
As the two fillies walked back to the schoolbuilding, they were met by the sound of a filly arguing.
"But why should Trixie have to clean up aall the leftover cake and not even eat aannnyyy of it?!" Trixie wailed.
Pinkie and Twilight looked at each other. Pinkie snorted, and before they knew it, both of them had exploded into laughter.
As she laughed, Twilight thought, even though today had gotten off to a bumpy start, so far, it was a pretty great day.
