DEAR ABBY: My high school graduation is right around the corner, and I have a problem with it. About eight years ago, my dad had an affair with a woman from his office. I'll call her Rosemary. As a result of that (and other stuff), my mom divorced him and moved out of state. Dad got custody and ended up marrying Rosemary about five years ago.
My problem is, Mom plans to attend my graduation. Given the fact that she despises Rosemary -- and I do, too -- I'm uncertain as to whether I want my stepmom to be there. I think it would create friction, even though Mom says she doesn't care if "that woman" shows up or not.
Personally, I'd like to ask that Rosemary not attend. Please let me know if it's my right to make the final decision for an occasion that's supposed to be "my day." -- MUDDLING THROUGH IN MINNESOTA
DEAR MUDDLING THROUGH: Yes, it is your day. However, since your mother doesn't object, for the sake of family unity your father's current wife should be given the courtesy of an invitation. Please remember that it isn't your responsibility to be a peacemaker. I hope you'll enjoy your special day. Congratulations.
