Should I wash my roomates' dishes?

I live with two other girls. And recently I've noted that they've been hushing something about me. About how I don't to chores. Which can be true, to some extent. So today when we finished eating our dinner, I went to take a shower and could hear them saying they would leave the dirty dishes so that I'd wash them. Should I do it and bow to their comments or just leave the dishes there, so they make a more confronting decision. Ideas, anyone?
