This is actually kind of tough, humans are so complex it’s difficult to just outright say one specific type of person is boring.
That said, if I had to pick one type of person, it’d probably be the kids who grew up rich, frat and sorority folks, someone who’s parents paid for their 60k a year private university. You know the type, probably. I just don’t have much in common with those types of people, and they generally just have… bland personalities. They all like the same things, they all act the same way. Not always, there’s exceptions of course. But generally that’s how it is.
