Quirky things you do...

[Majingir]

Don't know if this one counts since it's more smart/convenient than it is "quirky" but I keep a "log" (mainly just notes on my phone, but also a closet with things labelled) of "house maintenance" items. Lightbulbs are the main one, so if something goes I'll know the exact thing I'd need to replace/maintain it.

I'm not an electrician or anything like that, but I at least know the basic things for lighting so I'd know which bulbs/fixtures and on would be better, or brightness/colour temp and so on.

Same goes for other things too, if a part would need replacing, it's a good idea to know exactly what everything is. House wall needs touching up, I'd know the exact colour it already is, a filter for the furnace or a fan needs changing, I know the size/model.

I do the same or similar. I suppose mine is geekier than yours, though. I have an Excel file with bulbs, part numbers, what rooms, and a map of the electrical breakers. My house is old; it was built by my great-grandfather in the late 1930s/early 1940s when he was getting into the electrical business before changing careers later.

For some context, earlier in life, I was an automotive parts manager [and eventual regional manager], which is where I picked up on that. I miss those days. Life was so much more simple back then.

Mine is way weirder, I have to tap my foot a specific number of times before I can leave a room.
