Stop in for a cup of coffee

Well since I got done with front brake lines I migrated to the rear lines. Ripping all the old stuff out I managed to bash my head on the lift hard enough to clack my teeth and knock me somewhat senseless. I decide to sit down in the house and collect my wits, stop the blood etc. not deep but just hurt like a mother. More pissed off at my own ignorance than anything else. Wife sees hand on head with towel asks what happened, with genuine concern in her eyes. I explain I raised up and walked into the lift arm. Thinking that pretty much summed up my brilliance. She proceeds to ask, well how did you do that? Now the mature loving husband would have simply explained. But....... the smarta** sitting there with bandage on head and growing goose egg replies. Well I was out checking the mail, when lo and behold a two post lift was sailing down the street, as I opened the mailbox the lift arm clipped me. I will spare you guys and one lady the ensuing conversation but suffice to say me and the hound got tossed out of the house and are back out in shop.
