If you're kind to enough of them, they put you on a block list.
They were such sweet kids, they'd turn up at my door with the thatch of raspberries out front and try to share their word with me, and I'm me, so, I fed them.
Then it was one of the wee 'elder's' birthday, so I made him a cake, and all the little lads came, and they asked about my books and board games and CCGs, I was just a nice frumpy middle aged Jewish lady, I was no threat, so I fed them and made them cakes and took them to the local gaming store and listened when they talked.
One loved yu-gi-oh cards, and it turns out, one of the other wee lads, we'll he loved him back, so I got them in touch with some resources so they had support and a different way to pay for college, they're still together 15 years later, they have dogs, they send me ecards on their birthday. No-one figured out I'd.helped them, I was just the nice lady who made them tea and listened when people were slamming doors.
The next one really wanted to be an artist, so I left out art books and resources, my eldest shared their coptic markers, they draw comic books now, no idea why his folks were insisting he needed to be a dentist, but, he's not a Mormon anymore, (not a Jew either before anyone makes any counter conversion claims).
The first 2 lads were the only dramatic ones, the rest went back into the network but, like Hugh of Borg, they spread the word, sometimes I'd get Mormons from other cities come and make the journey to break bread at my Sabbath table and be seen.
I still think very fondly of that time.
Many of those boys still email me now and then.
Most of them aren't Mormons anymore.
Someone higher up spotted the pattern and suddenly no more Mormons at my door.
I was blacklisted, for kindness.
So there you go, if you don't want Mormons at your door, just love those kids for a couple of years, feed them, help them, and eventually, no more will be allowed to visit
