You know how when you buy a new car and start seeing the exact model and color combination everywhere? Well, being a parent is sort of the same thing. When you become a parent it opens up your perception to new ways of seeing. You become hyper vigilant to all the micro dangers and joys around you.
It’s fun to notice the codes and logistics around trick-or-treating on Halloween. For instance, houses that have both lights on and decorations are the best houses. These are people that enjoy seeing all the fantastic costumes. You can see their personalities bleeding through - some people go full scary, some funny. Some people want to be more welcoming and sit by their door.
If you don’t want partake but have a popular neighbourhood, you turn off all your lights. If you don’t want to be bothered but don’t want to seem impolite - you leave a bowl of candy at the door, with a take one sign.
