That's an interesting saying. I agree, mostly because hey, we're young, we're supposed to act stupid. But at the same time, there are some things to be grown up about. If the government says we're an adult at age 18 (which I am, in case you really wondered), then I suppose it's time to start thinking about what kind of grown up you want to be, and start adapting. In all honesty, growing up sucks.
