Things you do or like that only you enjoy

Do y'all have a thing you do/like that no one else you know (or a few) enjoys?
I, for example, like watching Tokusatsu shows, and the only other person I know that also does is my best friend.
Here's another example of mine: I like "drawing" pixel art. Basically, I count the squares of a character's Sprite and start drawing that in a squared notebook. It's weird, but it's fun.
