Ya know, that reminds me of something that a woman said to me when my daughter was a newborn. I had her at the dr. for a checkup, and a woman said to me "she looks NOTHING like you". What a stupid thing to say to a new, first-time mother! I just said "well, I can guarantee you that after 37 hours of labor, she IS mine". Geez, so she looked like her father, is that so unusual?
People just don't think. I try not to let them get to me because their opinions don't matter anyway.
