You never know how weird your upbringing truly was until you're in a room of people with their mouths agape, completely confused by a story you thought was normal.
While every region has its cultural nuances, there are some traditions so specific to a town, no one outside a 5 mile radius will understand what you're referencing.
Happy haircut day. Anytime someone would get a haircut, if you noticed you would say "Happy Haircut Day" and the goal was to be the first one to say it to them. Didn't realize this wasn't a normal thing until college lol
In my childhood neighborhood, you could go to one house and get a handful of candy, a different house for a soda, another house for a cookie and yet another for a popsicle. Most of these people didn't have their own children, only the cookie house had kids but I think they were Mennonite and homeschooled.
