tonight was back to school night. why is it that i talk like an idiot around parents for 45 minutes, but i'm just fine with kids all day long?

so, yes. i want to go to bed right now. emotionally and physically i am completely exhausted. last night i somehow removed a peice of clothing in my sleep and put it on the bed next to me. how did i do this? i have no idea. in fact, it kinda freaked me out when i woke up. am i that tired?
