I think I hit my wife for walking on my bag and destroying my crisps
Why would you hit your wife over that?
Because she has no respect for my things.
I'm sorry that your food got ruined, but you can't hit your wife because of it. Next time, don't leave your crisps lying on the floor.
Yeah I know but she deserves it, she's crazy.
You should never hit anyone for any reason, let alone such a petty one. You ought to learn to try and control your anger next time.
