It sounds like she went back to her immature days as a teenager. Its amazing the way friends grow up or don't grow up. Slamming someones parents is no way to get back into touch. I'm sorry that happened. Perhaps she was just trying to be funny, but it was insensative. Two ways to deal with it. Let her know she was out-of-line or ignore her. Whatever feels better for you. You have been out of touch way to long to let it bother you. If thats her first comments after so long then she probably is not going to become a close friend again. Just my 2 cents.
