I'm going to steal this lady's stuff.
Why would you steal her stuff?
I can't stand her. I'm going to steal a lot of her stuff so she'll be upset.
I get you're annoyed, but the answer is not to steal things. You'll just get in trouble, possibly with the law. Try to just avoid her.
Only a stupid man would be caught by the law with someone else's things.
All I'm saying is you should avoid trouble and not steal anything at all. If you don't like this woman then you should just confront her.
