How do I criticize my parents if I still live with them?

From my experience, criticizing my parents never takes me anywhere, and I still live with them. I would say you could hope for better by peacefully airing your grievances. I know everyone is different, but my parents and most I know don't really listen. You could try but it personally never got me anywhere. So what I do, I suck it up and try to cheer myself up when they get so frustrating that I cannot stand myself. Either way, there's only so much you can say and/or criticize when they are the whole reason why you are clothed and fed.
