Once they get to Rarity's, Twilight gives a soft knock on the door. After a few moments, the door opens revealing Rarity in all her glory.
Spike is drooling once again, but this time it's not because he's hungry.
"Hi Rarity. How are you doing today?" Twilight says as Rarity steps aside to let her in.
"Why i'm doing just wonderful darling! If I may ask, why the sudden visit?" Rarity asks, genuinely confused as to why her friend would suddenly show up at her door like this.
"Oh no reason! I'm just here to pay a visit to a friend." Twilight says politely
"Oh! I see. Well thank you so much darling. I appreciate you coming by to visit. " -Rarity stares intently at a sowing machine as she pushes fabric through it.- "Since you're here, would you mind helping me out?"
Twilight gets off of the couch she had sat on when she had first got here. "Sure! What is it Rarity?"
Rarity pushes Twilight into the center of the room and leaves, returning with a dress enveloped in her magic. "Could you try this dress on for me? I need a model for my dresses and since you're here I thought you could do it."
"Sure, Rarity. Of course i'll help." Twilight said, a bit taken aback by the sudden action.
"Oh thank you darling. Now, try this on." Rarity shoved a dress into twilight's hooves as she said this.
What followed was a flurry of work, cloth, and dresses. So much so in fact, that Twilight eventually lost track of time. Spike simply took a nap, and was in the middle of a very pleasant dream. When they finally managed to leave, they were sent off with a happy goodbye and a "Thanks for your help, darling. It means so much to me that you came for a visit." from Rarity.
As they trotted away from Rarity's home, Twilight looked up to the sky, only to realize that it was quite dark out.
"I must have been trying on dresses for quite a while. Just look at how dark it is!" She lifted a hoof to the sky, gesturing to the setting sun over the horizon.
"Yeah, it is pretty dark out. How long do you think it's been?" Spike said, yawning.
"I don't know..." Twilight said in response to the dragon's offhanded question.
She decided that she would go rest at home. All the stress from Rarity's dresses and the boredom that came along with it, as well as the uneasy feeling she's been having all day from wondering about her friends strangely generous behavior, has made her tired.
Just as she was about to leave to her home, followed closely by spike, she was stopped by Rarity, who had trotted up beside her without her knowing.
"Twilight, wait!" Twilight froze at the sound of Rarity's voice in her ear. She relaxed, however, when she looked in the direction the sound had come from and saw Rarity.
"Oh it's just you. You...scared me there...for a second..." Twilight said she tried to catch her breath. Once she did, she straightened and looked at her friend. "What is it, Rarity?"
The unicorn fashionista had a worried look on her face as she said, "Oh dear, um...sorry for scaring you. It's just that um...well, I have this for you..." -Rarity pulled a beautiful dress out of a bag that she had brought with her.- "Here take it. I want you to have it."
Twilight looked at her friend like she had just slapped her in the face.
"Well, what's wrong, darling? Do you not like the dress?"
Rarity flinched as Twilight teared up and began to cry, sitting down on her haunches and covering her eyes with her hooves.
"Well now! I know you don't like the dress but-" Twilight cut her off mid sentence.
"That's not it!" She said through tears and sniffles.
"Then just what is the matter, dearest? I can't help you if you don't tell me." Rarity said, looking even more worried now.
Twilight sniffled, wiping the tears form her eyes as she got back up onto her hooves. "It's...it's just that...You've all been doing such wonderful things for me today, and i've done nothing to repay you for your kindness."
Rarity looked confused at this. "Just what are you talking about dear? All of us? The only one I know who gave you anything today is me."
Twilight spoke in a tone that told Rarity she had been holding this back for the whole day.
"Ever since I woke up this morning, people have been being so kind to me. First the whole town of ponyville is waving at me, and i've been getting greetings from ponies I don't even know. Then Apple Jack offers to make me breakfast, and now you're giving me this dress. I feel like i'm taking advantage of all of you, because I haven't done anything in return."
Rarity looks at her friend. "Well, that's what friends are for ri-" Twilight cuts her off again.
"I got greeted by ponies I don't even know, Rarity! ...I don't deserve such kindness. Not when I've done nothing to earn it."
Rarity watched her conflicted friend for the longest time. Then, she wrapped her hooves around her neck and said, "You do deserve it."
Twilight opened her eyes, which had been closed as she continued to cry silently, tears streaming onto the ground. She looked at her friend. "I do?"
"Yep!" She heard spike say, as he patted her back reassuringly.
Twilight laughed. "Thanks, Spike."
Rarity pulled back, her hooves still present on her fellow unicorn's shoulders. "You do. Everyone else in ponyville knows it as well. You deserve all the happiness you get. You are an amazing pony twilight. and if anyone knows it, it's me."
"T-thank you, Rarity...that....means a lot to me. More than you know." Twilight stood up, righting herself as she wiped her eyes, no longer feeling the urge to cry.
"You're welcome!" Rarity said, smiling. "Now go on home and get some rest. You need it."
"I will." -Twilight began trotting back home.- "Thanks again!"
Suddenly, she was stopped by Rarity again. As she wondered what her best friend could want now, Rarity said, "Oh, and, Twilight?"
"Yes, Rarity?" Now it was Twilight's turn to be confused.
"Make sure to try the dress on when you get home, okay?"
Twilight rolled her eyes. "Of course, Rarity."
Twilight and Spike made their way home, the day finally over.
