I live in a pretty new development. I spent from 4th grade till now (11th grade) here, and just now they finished putting houses in the last lot. As I was growing up there were always unfinished houses and big foundations and stuff to explore. We used to play hide and seek with like 15 kids throughout 2 or 3 unfinished houses and the woods around it. That was fun, back in the day.
Unfortunately a lot of those kids became douche bags as they grew up, their parents got divorced and they moved away, and other stuff. I don't have a single friend in this neighborhood anymore.
