Quick dinner with ... Ang [Lee] and his wife Jane who's visiting with the children for a while. We talked about her work as a microbiologist and the behaviour of the epithingalingie under the influence of cholesterol. She's fascinated by cholesterol. Says it's very beautiful: bright yellow. She says Ang is wholly uninterested. He has no idea what she does.I check this out for myself. 'What does Jane do?' I ask.'Science,' he says vaguely.

A single person is a manageable entity, whom you can either make friends with or leave alone. But half of a married couple is not exactly a whole human being: if the marriage is successful it is something a little more than that; if unsuccessful, a little less. In either case, a fresh complication is added to the already intricate business of friendship: as Clem had once remarked, you might as well try to dance a tarantella with a Siamese twin.

Marriage is like a series of opposing reflections, inverse images getting ever smaller like nesting dolls, each one of your trying to squeeze yourself smaller to fit inside the hopes of the other, until one of you cracks or stops existing.
