The reason I ask this is because when I was on the field way back in the day - I really couldn't be bothered if the householder was interested or not. If they took literature and paid for it (we asked a certain price for literature before it all became on a donation basis) it was a bonus, plus meant money for a cooldrink / tea & cake afterwards.
Actually I would prefer it if they weren't interested so I could get away from the door - sometimes their ""conversation stoppers"" made too much sense and I couldn't answer back.
That meant I didn't convert anybody. Do you think most of the JWs' are like that today? I mean do the rank and file really care? Did you?
