It happens to everyone - sometimes, you have nights where you just can't fall asleep, no matter what you do. It could be for a number of reasons, or no reason at all. And this is what's happened now: you've been laying in bed for what feels like hours, just tossing and turning, and nothing seems to help. So what's left to do? Get out of bed and go wake someone else up, of course. If you're not getting any sleep, then why should they?( Ganked from bakerstreet )
