twist the knife

My son started preschool yesterday. He loves it. Okay, I know that I should be really happy but a part of me is so sad that he doesn't miss me. I know thats terrible and I did get the crummy side with my daughter when they had to peel her sad crying body off of me the first few days of preschool, but come on. This morning on the way he said "I so excited for school". what? Twist the knife, buddy. Then again when I see those other kids crying and reaching for their moms, I feel the sadness. You go boy.
