As a millenial I found I had a lot more in common with my Gen Z brother than I do with my boomer father. However, the little shit treated and thought of me like I’m a boomer. He’d consider my shitty FPS playing on console to be a sign “I couldn’t play games” (I’m a PC gamer).
I’d like to think he’ll mature and realise he was being a little cunt but I doubt he will.
