I think you have a passion and an obsession for something when it's not necessarily ubiquitous.
You're over there in the corner either thinking about the dead dog or whatever, you're bringing up your personal life and you need the space, and then somebody throws you a joke. Especially if it's an emotional scene, you don't want the joke.
I wish I had a little more ambition. But then what would I do? Turn down more roles with more vehemence? Me no likey worky.
