As the daughter of a mother who had me when she was 40 and a father who was nearly 41 when I was born, this sort of thing has happened to my parents and I for the last 35 years. PD was not a factor until 8 years ago. I always gently corrected my friends that they are my PARENTS, not my grandparents. My parents' friends and acquaintances accepted the news gracefully. :) Trish
