Uh I am not two faced really. Like even if I don't like someone and still act friendly with them it's not that I'm dragging them along or anything I'm more so just "haha I don't have the capacity to be mean to people I barely know and arguing makes me cry so I guess me and this person are friends sorta"
This one boy in my class, sits next to me, I absolutely hate his guts, but he's the only person at that school that even really talks to me. I still consider him my friend. Will I ever talk to him after I graduate? No, and I'm 100% sure he'll do the same. But are we friends? Yeah. I would never pretend to be friends with someone that's a shitty thing to do. Even to shitty people.
I hate talking to people because I'm bad at it. I don't know what to say and I don't know when and I don't know how. It's either take the risk of socializing and mess up so you can stick out like a sore thumb and now everyone looks at you weird, or disappear into the background. Disappearing is the less scary of the two options.
Also small talk is the single worst thing we have invented as human beings. Small talk should go die in a ditch. Like what even is the point. You can talk normally guys I swear no one's gonna explode if you just talk.
Point is, I'm happy with my personality and all but I don't like being "the weird kid" so I just kinda keep to myself. I don't pretend to be someone I'm not I just simply don't even talk.
