Dear Annie: My wife and I are in our late 60s and have been married for six years. We were both widowed. We have a great deal in common and are happy together. Our one bone of contention is her daughter. "Justine" is in her late 30s, married and living overseas. Yet every time she visits, she expects to get picked up and dropped off at the airport, despite the major problems that driving both ways can cause for us. Hints that she might want to get a taxi are blissfully ignored.
