Have you ever had problems with your mail being stolen? Just once, and it wasn't a problem.

I've got problems with that second answer. "I have had problems once, but it wasn't a problem." Are you saying that you've had your mail stolen once and it wasn't a problem? That's not what the question is asking. The question is asking if you've ever had problems, so by saying "just once" you are saying "yes, I've had problems". Maybe it wasn't a problem because your life is just one problem after another and so it fit right in?
