Is there anything sadder than a train
That leaves when it's supposed to,
That has only one voice,
Only one route?
There's nothing sadder.
Except perhaps a cart horse
Shut between two shafts
And unable even to look sideways.
Its whole life is walking.
And a man? Isn't a man sad?
If he lives in solitude a long time,
If he believes time has run its course,
A man is a sad thing too.
(trans Ruth Feldman and Brian Swann)
