Door to door christians?

First off, I'm not religious. However I am polite! So when a Christian woman came to my door yesterday and asked if I thought about the Japanese disaster, naturally I said yes, that it is very sad. She then asked whether I thought the disaster was foretold in the bible, to which I replied I doubt it. She flicks to a page that says something about nations rising against nation, and earthquake after earthquake destroying the world etc etc. I told her I'm not religious but she pressed on, gave me reading material and said she would return next week to discuss it further. I just cannot be rude, I dont have it in me; so what would you have done in this situation and what would you do when she returns next week? Helpful answers are much appreciated!!
