“You never can tell, though, with suicide notes, can you? In the planetary aggregate of all life, there are many more suicide notes than there are suicides. They're like poems in that respect, suicide notes: nearly everyone tries their hand at them some time, with or without the talent. We all write them in our heads. Usually the note is the thing. You complete it, and then resume your time travel. It is the note and not the life that is cancelled out. Or the other way round. Or death. You never can tell, though, can you, with suicide notes.”
