My roommate and I both walk out of our rooms at the same time, preparing to go to bed. She's in her pink bathrobe with a towel in her hair, and I'm in a tshirt and pj bottoms. We stand at opposite ends of the hallway, facing each other, and silently wave.
"How're you doing over there?"
'Good. I'm putting this stuff on my knuckles because they're all cracked and dry.'
'My knuckles' (I hold my hand up, to illustrate). 'They're really dry.'
"You don't even want to know what I thought you said just now."
'Do you really think that's something I would even say out loud?'
"...well, you ARE getting more comfortable around us..."
'Not that comfortable.'
