I was young and stupid. Remember floppy disks? Yeah, we still had them when I was studying. Went to a computer cafe, rented a PC and DOS was already booted up (I'm an old fucker). I didn't want to reboot because PC rental was metered. I inserted my floppy disk and got infected by a virus that deleted my work. No git back then and my backup was on the same disk (fuck me). Back home, rewrote the whole thing from memory.

I got mad and wanted revenge. De-constructed a floppy disk, replaced the magnetic media with sandpaper and went to each and every PC on that computer cafe.

It was closed for day.
