I love speculating about solutions to problems in mathematics. I have no interest whatever in sudoku. But I do look at chess and bridge problems in newspapers. I find that relaxing.

And an equation is the same whether it's written in red or green ink

I think goodness is about how person behaves to person, and also person to world, to nature.

How rarely these few years, as work keeps up aloof,
Or fares, or one thing or another,
How we had days to spend under our parents' roof;
Myself, my sister, and my brother.

All five of us will die; to reckon from the past
This flesh and blood is unforgiving.
What's hard is that just one of us will be the last
To bear it all and go on living.

I love Barbados, it's really relaxing.

When I realised that I had feelings for men as well as women, at first I was worried and frightened, and there was a certain amount of 'Who am I? Am I a criminal?' and so on. It took me a long time to come to terms with myself. Those were painful years - painful then and painful to look back on.
