After school one day, a young first-grade boy was sitting at the kitchen table, eating his afternoon snack, when he blurted out, "Mom, the teacher was asking me today if I have any brothers or sisters who will be coming to school."
The boy's mother replied, "That's nice of her to take such an interest, dear. What did she say when you told her you are an only child?"
She just said, "Thank goodness!"
