Most people are superficially charming but once you get to know them are kinda jerks who hide it pretty well underneath the mask of reasonably good acting. How else would anyone get past a job interview? Life requires that you be able to survive on whatever wage you're making. If you can't ingratiate yourself to a host who will pay you to exist in their domain, you're in deep trouble.
Life is acting school and some people are way better at it than others. So, for example, if you meet someone you instantly hate the second you lay eyes on them, if you make a bad face when your brain cringes, that will definitely not win the award for best acting. If, OTOH, you can meet someone you loathe instantly and convince them you love them, yer goin' places man! The faster you convince them that you love them, the better. Or maybe not. Gotta be careful because it's not always desirable to convince a stranger you have an unexplained affinity for them.
For example, when it's gonna cost them to have you around in the future? Not such a great idea to express your undying love for them in record time. In that case, you have to convince them you're not needy. And even convince them they need you. At which point, it is OK to express your disdain for them because they have failed the acting test by revealing their failure to not need anyone.
The entire point of socialization is to trick other people into believing they need us. I definitely couldn't fool myself. Unfortunately, I never could fool anyone else either. When I was something like 17, I used to look in the mirror and wonder how the hell I was ever going to win any acting awards with this face and this body language. I just knew it wasn't gonna work. Oh that didn't stop me from trying. Because I knew I had to try and I might just get lucky (sometimes our perceptions of ourselves magnify the tells). What else can you do when you look in the mirror and you know that what you see looking back at you is everything you have to work with? Well, the first time I did that was a terrible realization that I was FORKed with a CAPITAL FORK. I liked what I saw but I knew no one else would. And that was the quandary. If you actually want to be unpopular, you probably will be. If you have no choice but to be unpopular, you still will be. If you have no choice and you like it anyway, man, yer done!
Is any of this real? I don't know. Maybe I just don't know myself. (TBH, it's just been a really long time since I've had a good rant)
