I've never had white teeth. To be honest, I've never been told to do any of those horrible things - get your teeth whitened or your nose straightened.
I was always very curious as a young man about why older writers who I met seemed so indifferent to what was going on, whereas I, in my 20s, was reading everything. Everything seemed important. But they were only interested in the writers they admired when they were young, and I didn't understand it then, but now, now I understand it.
