You have enemies? Good. That means you've stood up for something, sometime in your life.
Essentially, I'm untrained, so I just go with my imagination and try to put myself as solidly as I can into the shoes of whatever person I'm going to be playing.
I struggled with being a Latino growing up in Los Angeles. I felt very American. I still do. I went to 35 bar mitzvahs before I went to a single quinceanera. I could talk all day about my culture and what it means to me.
