Sheesh! How aggravating for you. I think I would want to just bang my head against the wall after every convo with this parent. I totally agree with brightsparks. At this point I don't see how things are going to get better. If you can, I would put them on probation. Don't make the mistake of hanging on to this client in the hopes they will change, only to suffer yourself and have your days become more and more difficult and unpleasant. I've done it, twice, and it was the biggest mistake!
