I once had a boyfriend who couldn't write unless he was wearing a necktie and a dress shirt which I thought was really weird because this was a long time ago and no one I knew ever wore dress shirts let alone neckties it was like he was a grown-up reenacter or something.
I don't think actors should ever expect to get a role because the disappointment is too great. You've got to think of things as an opportunity. An audition's an opportunity to have an audience.
