p.s. last post continued *yawn*

So I'm closing my eyes and a thought pops into my head. Do birds sleep at night? I don't think I ever learned that. You don't see them flapping around at night. Do they have a curfew? After what time do you just start to not see them flying around? It's way too early for this kind of crazy talk. But really...did I just miss the 'when birds rest' day in school? *yawn* I swear I have only had water to drink today.
