We'd said we'd keep in touch. But touch is not something you can do from distance. Touch is not something you can keep; as soon as it's gone, it's gone. We should have said we'd keep in words, because they are all we can string between us-words on a telephone line, words appearing on a screen. But they cause more complications than clarity. On the phone, there are always voices in the background. On the screen, there are always sentence saying he has to go.
