"Did you have a nightmare?"
"There's plenty of room for the both of us."
"There is not enough room here for both of us."
"It's cold. We should try to conserve body heat."
"You're not even going to notice because you'll be asleep!"
"We've only got the one bed between the two of us."
"Quit stealing the covers."
"It's better than sleeping on the floor."
"It's either this or you sleep in the tub."
"We're sleeping in the same bed, not together!"
"Do you have any idea what time it is?"
"You sleep on top of the sheets."
"I'll sleep on top of the sheets."
"I'm scared. Can I sleep with you?"
"You're scared? You can come sleep with me, I guess."
"I have to sleep closer to the door."
"I can't sleep this close to the door."
"Stop getting up so early. You always wake me up."
"Stop staying up so late. I can never fall asleep."
"Just don't try cuddling me or anything."
