Well, you create your own persona, don't you? And you have to live with that. But the people that I meet, they don't think that I'm a lunatic. And if they do, then that's OK, because it means that I'm playing the parts all right.
If they didn't call you a tough guy, then what else would they call you? Something worse than that? I'm playing parts, and if they call you that, it's because I played the part right.
