I don't wanna do the dishes, they can wait
Are you sure about that? You don't want to upset your family, do you?
I'm sure that if I leave the dishes till morning they still wouldn't be done.
While I know that doing the dishes is something that is a very mundane and a boring thing to do, but I would not recommend that you leave them overnight because there can be bacteria and all sorts of hygienic disadvantages if you delay it. Why don't you go and take care of the dishes right away, so that you are free to do whatever else you want after you finished?
My mom sucks ass, I'm not doing anything for her.
Regardless of how you feel, it is still your duty to take care of the dishes. It's a boring task, but it will only get more difficult if you leave it overnight, because food will dry onto the dishes. The best thing to do is to take care of this job and get it over with.
