I would say probably, yeah. As you get older you just learn to give less and less of a ****. You are the way you are, and it's that thing of being set in your ways. It's a like it or **** off situation. As young people, society constructs this culture of caring about how you should be perceived 24/7. And then you're guided less and less by societal norms as you get older, I guess it just comes with time and experience. Of course, it can't be said for every 'mature' person though.
I ****ing hate people who generalise.
