From an e-mail I received:
Your comment about discipline and how to work with youngsters reminded me of a time when my son, Adam, was two years old. Every thing out of his mouth was No, No, No!
My husband had just had it with him and said, “Adam, don’t you say ‘No’ to me again; I’ve had enough young man.”
Adam looked at him, full of steam and said, “NOT!”
I couldn’t help but start laughing. You are right. “Not” doesn’t have the same effect as “No.”
Thanks for bringing that back to mind.
