I once bought a specific type of microphone stand…for a type of microphone that I don’t own.
I forgot about it almost immediately, and when it showed up after a week or two, I couldn’t remember buying it. But there it was, in my account history, and although I couldn’t remember buying it, I was fairly certain that I had actually done so. But I couldn’t remember why. I don’t recall having any plans to buy that type of microphone.
Bizarre. Maybe I’d had a few. It’s still a mystery
