My passion and energy get mistaken for anger.
I drank for about 25 years getting over the loss of my father and I took the anger out on myself. I did a good job at beating myself up at sometimes. I don't drink anymore but my alcoholic head occasionally says different. 'Nil By Mouth' was a love letter to my father because I needed to resolve some issues in order to be able to forgive him.
Growing up in a particular neighborhood, growing up in a working-class family, not having much money, all of those things fire you and can give you an edge, can give you an anger.
