my wife is PISSED!!!!!!!!!!!!!!!

Ive posted this sign awhile ago, &, being that it is a two sided overhead bracket style sign,i decided to do the right thing.you would think that ive been maried long enough to know the rules, which, apperantly are: whats mine is yours & whats yours is yours. help me hear if im going to fast (for the rest of us men) . Hears a good example, I found this (air conditioner support bracket, i think) cleaning out a rental property,& thought,Angie could use this as a nice plant shelf, ill even mount it against the wall for her.She turned her nose up at it,said "no, its YOURS." Ok, guess ill pitch it, BUT, the more i looked at it the more it started to come together. So i took a grinder & cut of the parts i didnt need, and wala!!! sign backet. After mounting it to the wall i thought, ill just show her what became of that "junk" i tried to pass off on her.Guess what she said????? I THOUGHT U GAVE THAT TO ME!!!!Guess what i said??? nothing, after all, u do learn something while being maried 10 yrs.
