I did all sorts of jobs after drama school - working in a bar, as a teaching assistant. I probably learned as much from them as I did at drama school.
I remember opening my dad's closet and there were, like, 40 suits, every color of the rainbow, plaid and winter and summer. He had two jewelry boxes full of watches and lighters and cuff links. And just... he was that guy. He was probably unfulfilled in his life in many ways.
