I broke the boy after five days.
Friday, I had to work, so Rocky decided this would be the day. He, ahem, forgot his lunch at home, taking the chance that his dad wouldn't notice and I wouldn't have time to take the lunch to the school, thus giving himself the opportunity to avail himself of a hot lunch.
He underestimated me. I called the school immediately and informed them that I didn't want him to miss out on a nutritious meal, so I was bringing him the lunch, and only charging 44 cents a mile. I took the lunch into the office, and the one woman who works there gets him. I told her, "I normally would be coming in my bunny slippers and bathrobe, but I am on my way to work, so I won't get to embarrass him this time."
"Oh, that's okay," she said. "I have no problem embarrassing him."
She did. She told him sweetly, "Tell your mom I love her slippers."
Rocky is now working on earning back his privileges. And there is soup in the freezer just in case we need it.
