"Its nearly two in the morning, what are you doing up?"

"I'm pulling an all-nighter."

"I can't sleep."

"I'm having nightmares."

"Will you stay awake with me?"

"Why am I still awake?"

"I should have gone to bed now, but..."

"I don't think I can sleep after that."

"It's past midnight, why are we still up?"

"Do you normally go this long without sleep?"

"God, I wish I  could just pass out right now."

"I'm an insomniac, this is just normal."

"I work best at night."

"It's that late already! But it feels so early..."

"Can we stay awake together?"

"Everything is prettier when everyone is asleep."

"I like being the only person awake sometimes."

"I can't sleep -- I've tried everything!"

"Lets get you some sleeping pills."

"I don't want to fall asleep without you."

"I'll stay with you whilst you're up."
