The other episode went further, yet was more ordinary. A teaching assistant had joined his class, she was pretty and flirted with him, and once, when the staff had drinks after school, they kissed lingeringly in the car park. Then he drew back from her, with some relief. After all he had Lydia now. It was both a thirst and a blessing, the late renewal of his erotic life. When he was young he’d been too absorbed in the problem of himself to appreciate possibilities blooming around him everywhere. Now, how long before the women only looked at him with distaste, or pity? He thought that he understood his father at last, how he had accepted this pursuit of women as if it were in lieu of every kind of outward honour. Sex looked like a cheap trick from the outside, but in its moment it burned up the world. You could not have everything: the whole wisdom of life amounted to that. Whatever you had, was instead of something else.
