I always want to laugh at the sad stuff. You don't need to laugh at the other stuff. I'm not numb to these things. I still go into really dark periods about Sept. 11. I think it's kind of like bullies. Bullies are just scared and thin-skinned, so they have to become bullies as a kind of survival tactic. I think comics are that way, too.
