went to the movies

i went to the midnight showing of harry potter last night with friends. had a blast. i could hardly move by the time i got home. what is it about sitting in a theater that makes me hurt so bad? we only had a 1/2 hour wait but there is no head rest for my neck and my head was exploding . this happens every time i go to the movies. just one more thing i have to really think to myself "is it worth the pain im going to feel later" this sucks!!!
