so this happened to me yesterday, i was hanging out with a few of my relatives and we were doing a lot of stuff and we were having fun but i realized that when my relatives talk to each other they talk like proper adults because well, they are, like, they can swear and stuff, but when i talk to them they are like “yea buddy sure!!” or talk to me like as if i was some sort of young person, and even my friends do that same thing, all of them!!! it feels like i’m not part of anyone’s conversation which sucks but well it’s fine!!!
People mature at different rates. There are myriad reasons for this. But it’s OK to be a little bit immature for your age. There’s no shame in it and it’s very common. Being an adult mostly sucks, anyway. You’re already aware of it, so that’s a good thing. Pay attention to social cues and behaviors of your peers and you’ll figure it out.
