Ideas for my digital photo story.

I haven't really settled on a final concept for my digital photo story. I only have a vague idea of what I want to do, really. I'm thinking of taking and gathering candid shots of random people, complete strangers, on the street or wherever. I was inspired by street-style photography such as The Sartorialist and other blogs. For my narration, I want to talk about how we perceive and judge complete strangers and also wonder about who they are, what their story is and what brought them where they are at present. Basically, I'm aiming to discuss how unique each individual and their life story is, in a non-clichéd way, I hope. So, that's it. I'm not make sure if that makes sense.
