My Stay at home son

We are in the middle of a huge inspection at work this week. My kids have been very kind at not destroying my house while I have been working long hours. Last night I called to say I would be home late. "Like nine o' clock late?" said Zachary. I said, "I have no intention of being that late, but I dont know when I will be home." I kept in touch with the boys every 30 minutes or so, made sure they ordered a pizza, etc. I was deep in the middle of reviewing some medical records when the phone rang (It was 9:01) Zachary called me to tell me that it was after nine and I was still at work. "I didn't know I had a curfew," I said. "I was just proving a point mom, it's after nine"
I felt like I had a wife at home keeping tabs on me.
