I used to get up early on Sunday mornings and wash my wife's car before she went to church. First thing she would say when she got back, “you missed a spot”. Trust me, I know what it feels like to have someone, metaphorically speaking, kick you in the private parts for all your hard efforts.
I see the world from a devil's advocate point of view. The glass is half empty, as it were. Or as my c99 bio includes, part time raving lunatic.
