I don’t mind them any more than I mind a bunch of other dumb posts that people feel compelled to share for reasons I don’t understand.
And a lot of them do seem earnest, like they’re showing off a macaroni picture they’re super proud of.
If my adult roommate came home and showed me a macaroni picture they’re super proud of, I probably wouldn’t be personally impressed, but I would be happy for them that they’ve found something they like and are proud of.
