Damn I hate that kinda shit. I'm always the last one up if I ever have people sleep over, 'cept one time my friend was on my computer till 5 fucking am (we weren't smokin' or nothin' either) and I told him to get off at 3am cause he'd been on since 12. But yeah...I hate lightweights who put you out cause they can't stay awake, or they can't hold their weed/booze.
But yeah man, I hate sleep overs nowadays cause that shit always happens. Last time I slept at someones house then I watched TV till about 3am while my friend was in the other room on the PC, so I fell asleep in his bed =p
