Has an anyone noticed an inverse relation between "faking it" and actual ability?

Idk man. People that just aren't that capable seem to have the highest and strongest of opinions, it's almost like it's a defense mechanism for their own insecurity and lack of their own ability. I find the inverse relation holds quite strongly. It's troubling if they've the proper means of bothering you.

Anyhow, the context here is that my house mates don't like me. Idk if I come off as a prude and they see me stunting on them (they're poor exchange students) or if they dislike me because I'm socially awkward. The latter is probably it. They're not from here and probably have huge insecurities and they're probably just trying to survive but they come off as malicious at times, mostly because they are. It's been a pain in the ass for me anyhow, but yeah these kids are dumb. I'm the oldest and a grad student, they're all undergrads. If I can express it, I'm not even trying at life, these guys are like swimming against waves just to survive. That means do laundry, keep the pee in the toilet for some reason, stuff like that...
