RICHTERW'S PROFILE

Hello, guys.
so, i'm doing a game who already have a story, graphics, and a lot os stuff made, but as the game will have a non-linear feel, i need to put alot of NPCs in the scenario, and to give some little personality to them, but i'm not good at thinking what topics of small talk should be there?

Can someone help-me with those "Small-talk" lines? The plot will happen in a small north american-town, something like in the series Twin peaks.
It can be any NPC, like a old woman, a young girl, a police officer... You know, just random people...
