A childhood belief about church

I remember when I was about 9 or 10 I was over my friends house for the weekend. Well, we were enjoying a picnic lunch in her front lawn, when we overheard her mom on the phone "Get your bibles! Their gonna get us!" We thought sh was having some sort of vision or seizure or something, so we ran inside and asked what she was talking about. She told us that the Mormons were going around the neighborhood and jokingly said that if we didn't convert to their religion, they would send us to hell. Needless to say, we were creeped out for the rest of the day, looking over our shoulders for what we called the Hellraisers. We saw two men in suits walking down the opposite side of the road, and knew it was them. We took refuge in the van, and watched the men knock the neighbors' door. All we were thinking was "Don't open the door Brian, please don't open the door." Well, Brian didn't answer the door, much to our relief, and we were inside the house watching TV when the doorbell rang. We begged my friend's mom not to open the door, and she gave us the strangest look. We listened to her conversation with the men, and they turned out to be pretty mice guys. She invited them in, and we all chatted for a bit. They informed us that because of their faith, they had to do this every week for a year, and were only allowed 2 phone calls home each, and one letter a month. We felt pretty sorry for them when they left, and couldn't wait until the next time they would visit. Of course, out of politeness, we never called them Hellraisers to their faces, but still talk about it at parties.
