I prefer not to know, because the real answer might be pretty disappointing. My parents used to live next door to Jehovah's Witnesses. Not knowing this my father innocently asked their six-year old daughter if she would be dressing up for Halloween. She went and asked her parents, and came back a short time later and screamed at my father that they didn't believe in Halloween and that he shouldn't be encouraging such godlessness in her.
My parents chose to deal with their neighbors passively rather than passive-aggressively, which is unfortunate because they could have written a hilarious note, requesting that their neighbors, among other things:
-Please inform your children that it's not necessary to scream all the time.
-Please inform your children that it's not polite to wander unannounced into other peoples' homes and take food out of the refrigerator and/or cabinets. When this is done without asking some people call it "stealing".
-If you expect your neighbors to babysit your children when you go to work or run errands please at least notify us.
-Please ask your children to stop burning used motor oil in a large barrel in your driveway. We realize it may have been one of you who was responsible for the large cloud of black smoke that blanketed the neighborhood causing the fire department to send around a truck to search for the source. At the very least we hope that if it was your children who were improperly disposing of used motor oil they were doing so with adult supervision, but we've learned not to take anything for granted.
