Well because maybe it's a good thing to offer food to these kids who don't really yet understand the folly of their cult beliefs. At least I can give them a cookie or something for their efforts.
I let some Mormons come in once when I was in my early 20's because I wanted to confirm some things I had heard about their religion that they usually don't share with outsiders. We talked for about an hour and then I asked them to leave. They came back the next day with their leader, and we talked some more. Then they came back the next day with their leader, and his leader! At that point I just told them point blank that it was nice talking to them, but I'm never converting to Mormonism, so stop coming back. To their credit, they said okay and left. It was an interesting experience.
Well I'm pretty anti-mormon even though I live in Utah. I guess shouldn't be so hard on them, they're not bad people really and I have mistreated them quite often. They do have weird beliefs (in my view) but when you're raised with that mindset it's not really your fault for believing it. Our neighbors are mormon and they're always looking after us, shovel our driveway when it snows and check to see if we're doing OK. I'd like to think that's how neighbors SHOULD be no matter their religious ideas.
Fr. In most interpretations vampires are undead, beings that lose all the joy of living, no warmth, no taste except for blood, inability to have kids or sex, being weak to the sun/running water/garlic/holy ground, being unable to enter any residence without being invited, having to sleep in coffin with dirt from where you are born (which means you can't travel without bringing a whole ass coffin with you). Being a vampire would suck, now a daywalker tho....
