And she sets about settling into Ponyville.
She learns her way around - here's where she can buy carrots and bunched dandelions and clover sprouts; here's where she can get a case for her crown and cases for everpony else's necklace so they don't have to wear them or leave them lying around loose; here's a shortcut between Guiding's house and the tower the twins live in together. This is when this little town wakes up in the morning and this is when everything closes at night. This is what her friends do all day: Cherry Cordial farms and looks after critters. Brightblaze tinkers with gadgets kind of singlemindedly (though she also flies). Silver Streak plays violin and and reads and wanders around looking at things. Guiding Star does fortune-telling for spare bits and belongs to a dance group and volunteers for anything going on in town that could use amateur decorating (Joy is often with her when she does this). Joy also wanders around being sociable and helpful and cooks, itinerantly, for anypony who'll spare him kitchen space.
And Clarity learns the organizational system of the library, with Blueberry's considerable help, and she studies and explores.
And when she's been in residence for just shy of a week, she gets a letter from the Princess, which contains six tickets to the Grand Galloping Gala. Aww, that's thoughtful. Clarity's never been before.
She goes out to see which of her friends she'll run into first if she takes a meandering path through town.
"They'll be going. I haven't heard from them about it or anything, but I know them. They'll be going."
He shrugs, and produces a smile. "Anyway, I hope you have fun there. I hear the food's really good!"
"I've heard that too." She floats a stray daisy petal to her mouth and chomps it out of the air.
"Do you know if the chocolate cake here is good, or should I just go home and have an apple for dessert?"
Nom nom nom. "How'd you learn to cook?" Clarity wonders. "I'd have invited you to borrow my kitchen if the library had one, but it doesn't really, everything I keep around there is stuff that's good raw."
"I can do a little bit, but Morning - that's my mom - did most of it at home so most of what I know are the steps in longer recipes that were easier to do with me helping by magic. She makes good homemade hayburgers."
"Morning does them good! I've never had better at a restaurant. She gets them really crispy on the outside. Maybe when we're in Canterlot for the gala I'll bring you all to my parents' house and see if she'll make a batch. I'll write them tonight." Clarity makes a note of this.
"Mm-hm! Morning has tons. Argent - my dad - doesn't have so many, but still some. He goes and nets riverberries with them. It's excruciatingly boring."
"They just sit there, nineteen minutes of twenty. They don't even really talk, they just wait for riverberries to drop off the bushes upstream because they're too prickly to go pick. I mean, a unicorn could do it and Argent is one, but only if you're willing to maneuver the berry very carefully for like ten minutes each through the gaps in the branches, it's actually faster to net them from the water."
