至于我们，我们是15岁的初中毕业生，不再是小孩子了。

As for us, fifteen-year-olds, who are finishing middle school, we're no longer younger children.

我不再是小孩了，我不会再到树下玩耍了。

I am no longer a kid, I can't play around you anymore.

现在我知道我是属于哪里，不再是小孩的我是属于一些我想的的地方。

And I am back where I belong, no longer kidding myself that there is anywhere else I want to be.
