It's very true that you can be both selfless and selfish at the same time. What we tend towards, particularly in filmmaking, is this binary sort of, 'This is a good guy, this is a bad guy.' And I quite like the fact that life is a bit more complex than that.
All my freakouts have been pretty private and directed at family pets and/or people I have been dating for too short a time to freak out at in that way.
