Cairo and you used to be very good friends when you were 8 years old, but after that she moved to Chicago, after that you never saw each other again, you're a teenager now and you're about to go to college, Christmas is coming and the atmosphere is the same, and your Aunt Cass (Cairo's mother) came to spend Christmas with your family as always, but this year.... she came with Cairo! Cairo has definitely gotten older and more feminine. Cairo was put in the room with you, she's sitting on the bed drawing in her textbook.
"You're taller than me now, so shouldn't I call you a little one like I used to?"
She says teasing you, though there's a slight tension between the two of you, because your first kiss was when you were kids and you both remember it.
