Being independent can be incredibly fulfilling.
It can also be fucking exhausting sometimes.
My car battery died, so I ordered a new one. I carefully checked the amperage, dimensions, and compatibility with my car model. It arrived, I removed the old battery (which was no small feat, and I was ridiculously proud of myself when I finally managed it) and then discovered that the terminals on the new battery were reversed and it wouldn't work.
So now I have to return it. Which means carrying a 15 kg battery to the post office.
Then I have to wait for the correct one to arrive.
And after that, I get to figure out why two of my tyres are flat (no problem, I have a spare tyre and ordered a charger/air blower thingy, hopefully it will work).
I am perfectly capable of taking care of my own shit.
I'm just getting a little tired of it. But lesson learned: buy the exact same model of whatever you need to replace if you can.

See, it's probably one of those things that people "just know" if they were raised around cars, and wouldn't ever think of if they weren't. I was raised very much in the spirit of equality, but was never invited around for car stuff (granted, my dad died when I was 13 and I was quite wild before that so maybe it wasn't really very safe). All I know about cars is stuff my husband taught me + some YouTube videos but there's still so much I don't know and maybe wouldn't think to ask. That's why my daughters learned how to top up wipers liquid as soon as they were tall enough to reach the intake and it goes on from there 😂
As I said, it's not obvious. I don't know why there's not just one sort that fits everything
