I did. Really.
There’s no need to go into details, save that I spent the day being taught a course by a man who murdered his wife.
I’m not making this up. I’d give a cite if a) I could find one and b) I knew how.
It was a little weird. He’s a good instructor, but I felt a little unsettled when he would make comments like “Of course, this was back when I used to drink…” and I just knew half the people in the room were thinking “and you hacked your wife to death in a drunken rage?”
Anyhow. If this doesn’t fit the description of “mundane pointless stuff I must share” I don’t know what does.
