"Vincent-ism's"

Yesterday Vincent asked permission to do something. I told him no and he proceeded to keep asking. Finally I said, "Vincent! What part of 'no' don't you understand? The 'N' or the 'O'?" He got a very serious look on his face then about 5 seconds laters he said, "The 'N'!"

I'm so glad at least he understants the "O"!!!
