Dear Eric: I am a 76-year-old man. My best friend is a woman who is 75. Her son and daughter-in-law have an 11-year-old and two little children under three. The son very frequently asks her to provide child care for overnights and weekends. They are very active and seem to always have plans for ski and bike trips, hiking and camping trips, and out-of-town concerts and visits with friends.
