I am a very bright, educated 73-year-old mom. My adult children are rude, scold, reprimand me. What do I do?

Sounds like this problem is a long time in the making. Why do the girls favor your husband? What kind of pattern did the two of you start when they were younger to have this happen? You and your husband put your heads together and try to remember what got this behavior started in the first place. Then your husband is going to have to do something about it. His first priority is his wife, not his kids. Respect is earned, not automatic, so the kids need to stop with the disrespectful behavior and their dad is probably the one to shape them up.
