Teen bride?

Yes, my reply above was that if you want people to treat you like an adult and respect the adult decisions your making then you should act like an adult. In all ways, big and small. Basically, if you're regularly doing things--any things--that would make a 30-something-year-old roll their eyes and think "spoiled brat, I remember being that age, ugh, I was a mess", then you're not acting like an adult. Regardless of your age, if you are acting like an adult then people are more likely to treat you like one and respect your adult decisions instead of thinking they're the whim of a silly teenager.

It doesn't transform you into one obviously, but like I said it is a start. She was just giving examples I'm assuming. I feel like presenting yourself as an adult in the way you dress is involved in being an adult. LOL
