To me being an adult means doing what you like doing without caring what other people think.

If i like to play pokemon games, having pretend conversations with my cat, eating an entire cheesecake on my bed while watching anime at 2 am on a friday night, then that is my fucking business.

At least i like to have fun, while you spend your time complaining on the internet about people with different tastes than yours.

The two are not mutually exclusive.
