You have probably never lived in or near them. Things my jeet neighbors do on a regular basis 1) allow their children to ride bikes/scooters in the apartment hallways. 2) spit on the ground/litter 3) leave their fly infested garbage everywhere instead of using the garbage chute. 4) yell at their family members incredibly loudly after 10 pm. 5) exercise on the top floor at midnight (even though we have a 24/hr gym) 6) complain about people smoking within 10 feet of the front door (while disregarding their own cooking smells) I could go on, but I'd rather not waste mental sanity.
