My first experiences of academic friendship made me smile in after years when I looked back on them. But my circle of acquaintances had gradually grown so large that it was only natural new friendships should grow out of it.

There has to be chemistry in a duet, but if you go beyond the point of friendship and attraction, you lose something.

Blunders, no, only friendship binds us to honesty - attracting crypts of mushrooms in the wake of our snowboards.

Even where friendship is concerned, it takes me a long time to trust people.

But, based on my friendship with Evie as young mothers, I started going on freedom rides in 1966.
