I had a visit from JWs yesterday.

The opening question was "Do you think that the world is getting better or worse?"
I imagine that this is one of many questions that they could open with, meant to lead into a chance for them to talk about their beliefs. I understand that there was, or perhaps still is, a ministry training school that taught techniques like this.
What are some of the other questions that JWs use to open conversations?
