TITLE: How to respond to "I was never much good at maths at school."
QUESTION [57 upvotes]: We've all heard it.  I even got it in Norwegian recently.  It's number 1 on the list of responses to the statement "I'm a mathematician.".  Does anyone have any good comebacks?  What other responses have you heard?
