It's stupid that people make friends that they can't be comfortable and forward with

Coming from an introvert, I see it all the time in our world that everyone makes friends but they're never comfortable around them, always have to have makeup on or clean their entire house and still try to act unique whenever hanging out with their friends. All the time I also see the classic relationship wherein they're calling each other fake and whatever behind their backs and falling out all the time because they trip over their own pride. I only have one friend but I'm always comfortable around him and we're completely straight with each other. We actually have deep conversation and I can't imagine people wanting any other kind of relationship. People take themselves too seriously that they can never just relax.
