I did think of becoming a priest quite late on, when other boys were thinking of knocking over fences and going out with girls. I would have made a very good bishop: nice housekeeper, nice clothes - god, the clothes.

If you have to read to cheer yourself up, read biographies of writers who went insane.

You create a world away from home and make new rooms for yourself. But when you arrive back home in your old rooms, the world you've made for yourself ceases to be real. Everything seems to crumble. Anyone who's been sent away to boarding school can understand that.

I went to live in Barcelona in 1975, when I was twenty. Even before I went there, I knew more about the Spanish Civil War than I did about the Irish Civil War. I liked Barcelona, and then I grew to like a place in the Catalan Pyrenees called the Pillars, especially an area between the village of Flavors and the high mountains around it.

I first went to Barcelona in 1975 after university, and I stayed for three years. I learnt Catalan because that's what everyone speaks in the mountains. They speak English to foreigners, but what people say to each other is much more important than what they say to you.
