My grandparent’s desktop computer. I didn’t break the hardware, but i set the default font size in windows 98 to some ludicrously high value. That made it so large the OS became unusable and the dialog to change it back was also unusable. Probably a quick terminal command would have fixed it within a couple seconds but I wasn’t old enough to understand that and my parents weren’t very tech-savvy.

I think 5 or 6. I’d get to experience living in different cultures without having to abandon friends and family in my current location.

For decades I pronounced albeit like “al-bayt”, instead of “all-be-it”. I only ever saw it in writing, and never hears anyone say it. Meaning made also so much more sense when I finally heard it being said out loud. Eye opener.

For the Netherlands: Katwijk, even had a genetic disease named after it.
