When is this feeling like an adult thing supposed to begin?

When I had my first full-time job, my own appartment, and I had to get insurance. Buying insurance is a completely no-fun, serious, adult-only thing to do, but it felt good to be grown-up and on my own. I’m much happier as an adult.

The other day I was thinking to myself at work:

I was thinking how tired I am of dating from woman to woman and how I’d really just like to find one gal and settle the fuck down.

I was also thinking how that whole bi-girl on bi-girl thing doesn’t turn me on anymore. As a matter of fact it annoys the crap out of me because I know most of these girls are just doing it for an attention grab.

After batting those thoughts in my head for a while I stopped dead and my tracks and thought: “Holy crap! I’m a grown up!!”

The first time I voted (at age 18) I got an inkling. But once I’d started work full-time, moved out of home, bought my own place and become responsible for paying gas bills, electricity bills, council rates etc, I felt that adulthood had well and truly arrived. I was 21 at that stage.

That is what I meant, and you expressed it very well. Neophile, not neophobe.
