Children are often very sincere. While I am absolutely not one of those people who glorifies childlike innocence and thinks everything they do is special, I have to say that children are usually the most sincere people (when I was little I liked to glare at priests while they tried to shake my hand, while my mum did not share this... hobby). They will say what they mean and not see a reason to hide how they feel.
I am not sure where I'm going with this.
Tracey Emin has that childlike sincerity, I think. She can be vulgar, but I think it's more vulgar when people pretend not to be. We are not children, so to pretend to be as innocent as children would be lying. Tracey Emin puts things very simply in her work and in what she says. She deals with mature topics in a blunt, childlike way, and the raw, real emotion she conveys is moving and genuine.

I think if children's TV presenters were actually just big children like they pretend to be, they'd be a lot more open and blunt. I'd love to hear a Teletubbie (sp?) whine about menstrual cramps.
