When I think of Miley I think "Yep, when I was in my early 20s I did a lot of crazy stupid stuff, I just didn't have cameras on me when I did it", so I give the girl a lot of leeway. I think in 10 years, or less (it was less for me), she's gonna look at this time and think "Why did I do that? Why did I think that was cool?", I did. Seriously, there are some stories that float around about things I did back then that leave me wondering what the heck was going through my head. And the truth is, nothing was. I had no real responsibilities, though I didn't have her bank account, I didn't have to answer to my mom anymore, I could do what I wanted. So I did. Then I got bored of that and grew up. I doubt I'm the only reformed party girl.
Like Miley, I also never got in trouble with the law. Sure, I went out, partied, danced on tables, made out with people in bathrooms, had a good old time. Then I got in a cab and went home. Never got behind the wheel of a car after partying. Never drove a Lambo at 25mph (no seriously, why even bother Justin? If you're gonna get a Lambo don't drive it like it's a Prius), egged someones house, or caused my neighbors to call the cops on me.
I feel like Miley is doing the wild and crazy thing. I feel like Justin is doing the I'm above it all because I'm famous thing. I know I saw his mom on the View awhile back and her reaction to his behavior was basically "Oh well, he's gonna do what he's gonna do", because he's the paycheck.
