Conversation during dinner last week:
Jack: Target? You are going to Target after dinner? I want to go.
Me: Ok, you can go with me.
Jack: Is good behavior a requirement on this trip?
Me: (stunned by his appropriate use of the word "requirement") Yes, Jack, yes it is.
Jack: Hmm. Nevermind, I don't want to go to Target.
Me: (stunned silence at his ability to know his limitations)
