I'm a child and I understand what you parents think about us kids growing up too fast. It isn't that we want to have a car, kids, and leave the house. All it is that we want to do is to go and be independent and do things on our own. Kids are young adults at 12-15. When we become 16-20 we have this big change. We go through bodily changes and lots of other changes, but to us, it's for the better.
