Time travel in letters

“There’s a kind of time travel in letters, isn’t there? I imagine you laughing at my small joke; I imagine you groaning; I imagine you throwing my words away. Do I have you still? Do I address empty air and the flies that will eat this carcass? You could leave me for five years, you could return never—and I have to write the rest of this not knowing.”
