Beema - there wouldn't be a specific reason as to why it was always the younger ones. The only thing I can think of, since you were on a farm, is they were doing 'rural witnessing', and often you can be stuck in the car for ages before getting to the next house.

The reason we keep coming back if someone says they're not interested but doesn't specifically ask us not to come again is that attitudes/circumstances/householders change. The magazines that we most often present are released monthly, always with different topics - what appeals to one person may not appeal to the next. Many times people have said for years that they're not interested, only to have something drastic change in their lives, and they get to a place where they want to ask questions, and they become more conscious of their own spiritual need.
