why must my neighborhood try to be so neighborhoody

When I was driving home from work, I was momentarily flummoxed by a bunch of families decked out in costumes, trick-or-treating along my local neighborhood business district. I’ve since googled to figure out what it is and am now extremely annoyed because the family stuff is from 1-4pm and then the adult Halloween party is from 9pm-2am and I’m like “WTF I’ve only just started to get back into a US time zone sleep schedule and now I know there are gonna be drunk and noisy party goers walking past my house late tonight.”
