I think it's necessary to identify with anything - with any character you play, there's got to be something in common, so you can link up to that person, even if it's like one tiny thing. But it's equally fun to play somebody completely different, and trying to find what that thing is to make it.
I try hard to convince them it's important - but there's a history of discomfort with minorities voting in some parts of this country, so most especially the older people have to get accustomed to it.
I have always been - I think any student of history almost inevitably is - a cheerful pessimist.
