Any eyes on me - a late-night street sweeper, some dude texting in his parked car, the homeless guy talking to himself - make me feel uncomfortable when I skate. Everyone expects me to do certain things.
I don't think I could play a character that I couldn't relate to somehow. I'm not unfamiliar with frustration, anger, shame, helplessness and a load of other emotions that make up our psycho-soup. I try to focus on that frustration, that sense of unfairness, and multiply it.
