But about the drip drip of long-haul, no-end-in-sight solitude, they know nothing. They don't know what it is to construct an entire weekend around a visit to the laundrette. Or to sit in a darkened flat on Halloween night, because you can't bear to expose your bleak evening to a crowd of jeering trick-or-treaters. Or to have the librarian smile pityingly and say, ‘Goodness, you're a quick reader!’ when you bring back seven books, read from cover to cover, a week after taking them out. They don't know what it is to be so chronically untouched that the accidental brush of a bus conductor's hand on your shoulder sends a jolt of longing straight to your groin.
