Mom: "Hello Dennis, when are you leaving?"

Prager: I refuse to answer that question because if you knew, you'd spend the entire week worrying, "He's leaving on Monday" or whenever."

Probably she asks because you never volunteer the information.

Since she never knows, she spends all day every day worrying, "I wonder if it's today? I wonder if it's tomorrow?" Why do you not realize that? Shame on you.
