My sister stole something from me, I'm going to confront her about it.
I'm sorry that your sister violated your trust that way. I'm sure that must make you feel awful.
It's just very mean of her to do these things to me.
I agree, you didn't deserve to have things stolen from you. I think you should calmly talk to her and let her know how you feel. You should also work towards getting your items returned to you.
I want to f*^%$#@ her, wreck her home and all her money.
While I get that she has wronged you, what you're describing is a bit extreme and isn't going to rectify the situation. In fact, it will probably make things much worse. Take a moment to calm down and speak to her rationally.
