My son, David, 4, came screaming out of the bathroom to tell me he’d dropped his toothbrush in the toilet. So I fished it out and threw it in the garbage. Zachary stood there thinking for a moment, then ran to my bathroom and came out with my toothbrush. He held it up and said with a charming little smile, “We better throw this one out too then, ’cause it fell in the toilet a few days ago.
