Probably a prolonged awkward moment that I couldn't escape. In chatting to an old friend I bumped into, I let slip that I'd heard something bad had happened to them and asked how they were doing. Rather than answering clearly, they were super interested in finding out who told me in the sort of way that I knew it would be a very bad idea™ for all concerned to reveal that information.
I can't remember how I got out of that. I sometimes think I'm still in that moment and all this is a fever dream as my brain tries desperately to escape.
Honourable mentions: i) Zeroing the wrong partition on my own computer, all data unrecoverable. ii) Deleting all of a customer's data rather than the one part they wanted removing. Luckily, in that case there were backups.
It looks (parses) as perfectly fine markdown on Lemmy (lemm.ee), it looks like how the markdown says it should look. The person above seems to want to inject asterisks into what you wrote for their own reasons, you did nothing wrong.
You're not going insane... probably. I edited the post to use asterisks which I assumed must be the more commonly used italic markdown. It might also be that the ™ is right after the markdown character which I know can cause some parsers to choke. YouTube's comment system is a notable nuisance for this.
