OP here again. I don’t. I just don’t get at least some forms of it. I have been known to do some good pranks, but most other things people classify as “letting loose” aren’t my jam. I’m more of a books and tea person.
Originally I was thinking of people I’ve known that literally made me feel like I was talking to a child. I don’t know what that is, exactly, but low intelligence is a decent guess. Oh well, I’ll try different wording if it ever comes up again.
