When Tre cries

Lately when Tre cries he cries for "mommy". This is funny. You might not know why. But he calls me "memaw", and David is "Papa". So 'mommy' is just a fictional character, someone that the kids on TV cry for. So now when I give him a spanking, and he crys for "My Mommy, I want my Mommy,"  I try not to laugh!
