Yes, this resonates, though I try to resist the urge to curtail my sarcasm.

I do find myself using sarcasm in a self-deprecating manner more than I used to, as it feels less prone to misinterpretation, or at the very least, that most misinterpretation would be unlikely to be taken at someone else's expense.

or worse when you realize someone you were joking with was actually being completely serious

I liked the stories about the moon landing not happening for many years (I'm 58), not because I believe it didn't happen, but because I loved looking into what would have to happen to cover it up and how impossible it would be to cover it up. It was a joke until I realised that people were starting to take it seriously. Alternative history was a hobby I was into, I was writing (terrible) stories myself and then they turned everything into "alternative facts" and made up history and took it for real and I just had to give up the hobby completely. It is no fun to write or read a story about a flat earth or people living inside the globe or aliens when you know someone actually believes it to be true. That's why we can't have nice things:

like half the worlds gone insane

I hope you're serious. I literally can't tell!

Probably wanted to make people angry

;p
