  When you're young, you don't notice your surroundings quite so much. Dirty or clean, new or old, the difference is obscure to children. Last night, I vistited an old burger joint my family used to frequent when I was younger. It really is a run down old place. And not run down in just a little way so that it's just different from when I used to go there, no, its the kind of run down that looks decades old. Maybe it's just my outlook
