My grandson (4 years old now), came over the other day, and there was a U.S. Mail truck parked in front of my house. I said, "you know, when I was a kid the mailman didn't use trucks, they used jeeps...!" He looked at me, and put his hands up in an Italian style and says, "and your just telling me, now...?" As if I'm withholding secret mail truck information from him.... Geez, when you least expect it, ya get zinged by a 4 year old...
