This occured this weekend and it fucking sucked. As it would have it i was volenteered "not by myself, but someone else nicer then myself" to help the old man pour and raise the cement around our bomb shelter so we could build a frame and walls around it. "My older brother lives in the bomb shelter at this time, and he is a pasty mother fucker." anyway so after 2 hours of hell in the arizona sun pouring cement we put bolts in for the frame around the edges of the cement. Well of course these present a triping hazard and the did a damn fine job of it. One day after getting out of the hottub have wet feet on cement=slipery feet. so i precided to trip over a bolt tried to jump up but ending up sliping and breaking my fall with my head and blacking out. And is this the end HELL NO! it gets better. after being uncouncious for a hour or so i stagger my way to my feet and im completely dizzy as fuck so i start stumbling and DOWN THE BOMB SHELTER I GO. 20' down stair still it again ends in concrete block into my brothers room. My brother at his computer going WTF and does he rush over to help NO THAT BASTARD WAITS TILL HE IS DONE WITH THE ROUND OF COUNTER STRIKE THAT LAZY FUCKING BASTARD. and thus my journey ends with a concusion and i have yet to go to a docter.
