I know how that is i'm 14 as well and my mother was worried about me going to a concert. It was a nice and small concert, it was in the big city here Phoenix was just 4 of my favorite bands. The best part is that since it's a small concert you get to hang out with the bands and talk to them and have a great time. They are the nicest people i ever imagined. They are so nice and caring. Just what worries my mom is what other people are there, which i know what worries you too. At least she is with people that will watch her. That's a good thing. I was just with my two friends so it was a bit different.
