I didn't give out candy last year or the year prior. Back in 2019 I counted less than 36 kids (this is because I remember making 36 individual baggies and had to take some the next day to work to remove temptation of eating them all myself lol).
I've only been at my house for a year but we got quite a few last year. I'm on the road at the moment and will be for the rest of this evening so I won't actually be able to hand out candy this year.
No idea. I even forgot it was halloween. My doorbell has been disabled due to the transformer of it making a loud humming sound at all times I don't want to listen to, and I'm always sitting with a noise cancelling headset on, so if someone was at the door... well, I wouldn't have noticed. I did an inspection of my house after the "party" had died down tho, and there were no eggs shattered across it or anything, so either it was only good kids that came by, or no kids at all.
The advantage with living in a flat contained within a locked entrance (converted farm house).. I haven't had to deal with any trick or treaters.
To be honest I'm a bit of a scrooge, and in the past at a previous property I used to turn off the lights to dissuade people from knocking on the door.
