Make him pay her back for it. Hit him in the checkbook, not the nose.My brother was the same way. Screw sh!t up to get out of doing it. We got in a fist fight once after for more then the second time he purposely mowed over something to ruin a push mower.
My mother had to buy those things. I think I'm still mad about it. I may sucker punch him next time I see him.
