children teach us not to have children. they are expensive, noisy, rude, unclean, demanding, etc.(actually that pretty much describes me).
don't mention what we miss, graduations, marriages, grandchildren, because if we didn't have these things, we wouldn't miss them. and don't mention how much you love your own kids. i love my four also. but if i didn't have them, i'd be loving the corvette sitting in my driveway. which isn't.
