Your Mom and mine must be twins!!! My Mom is constantly talking about us, her three kids, one at a time with the others behind our backs. Talks about us to our kids, picks on certain people, like my 18 year old grandson at Christmas time. She can make life very miserable, but does like your Mom, strangers and people in businesses are her friends. There is one key, though. My Mom has no friends her own age at all to do things with because of her problem. Try getting the book Toxic Parents by Susan Forward. I think you will get a lot out of it. I surely did!! Good luck!
