Do You Remember the Discussion?

Dennis Hodgman challenged his 11-year-old daughter to remember a conversation he had with her months ago. He said that she would forget the discussion, but now neither of them can remember what it was about. David Reese says there is no logical paradox as Lela does not actually remember the discussion at all. The thing she remembers is a provocation that dad said,. And she remembers that provocation, namely, you not remember this discussion.
