Not related to RP, but I gotta ask - why would someone disagree with everything you say?

My dormmate always has to disagree with me. It’s like he doesn’t even notice how weird it is, lol. Even if I say something as simple as “the wall is white” (and it’s definitely white), he’ll immediately say, “nope, it’s not.” I usually play along and ask him “why” or “how,” just because I’m curious about the kind of stuff he’ll come up with. He’ll start making up the wildest scenarios to prove his point, and eventually, he stutters. When he realizes he’s got nothing, he’ll just make up some excuse (while still in denial). I always ignore him, then shake my head (because there's no point arguing with him) and go back to my own stuff, kinda cringing inside and wondering, you know? i find it strange and I’ve been trying to figure out why he does it. (cause he always does it)

I could’ve just asked him straight up since he just did it again, but I don’t wanna make him self conscious. Sometimes i can use it against him and get him to do stuff because he tries so hard to prove he’s right. I’ve tried googling it and even asked ChatGPT, but no luck finding a good answer. So yeah, that’s been bugging me for the last week.

Also, is there like a forum where people talk about psychology or human nature or something? because i have some questions to ask and i want learn more about human behavior.

Last week i was a lil bit depressed when I realized that we all fucking die. I’ve always heard people say it but it took me some time to comprehend that we will all fucking die and we had no purpose. :0
