I know this girl who's pretty nice and we're good friends, but her best friend is kinda mean sometimes. Not mean like a bully, just gets mad easily. I get the impression that her bff judges people a lot. Like, if I'm late to a meeting, or just says something stupid to fool around she'll give me a look and maybe say something in a demeaning tone of voice.
I've read time and time again that which friends someone hangs out with will have similar personalities as them and is a good indicator of whether or not they might be mean and stuff, but is that always true? I kinda want to be in a relationship with her and she's really nice to me and to her friends, and she's really friendly, but she's also shy and her best friend is also shy. (Or, just really judgemental and refuses to associate with those she judges to be unfit for her or something really stuck-up like)
So is she actually a nice person or just pretends to be nice? Maybe passive-aggressive? Maybe she just happens to be BFF's with a really mean and judgemental person? And why would someone pretend to be nice but aren't anyway?
