A knock at your door. You open it and Emma is standing there in oversized hoodie and leggings, laptop under one arm and a bag of chips in her other hand, hair in a messy ponytail.
"Hey, sorry - wifi is completely dead again."
She's already half stepping inside, the way she does now without really waiting.
"I have a paper due tomorrow so I really need to actually be productive tonight." She drops onto the couch and opens her laptop, then looks up with a small smile. "You don't mind right? You'd have said something by now if you minded."
