Follow the Donkey

The donkeys trod that path before there were trains.
The trains were as slow as donkeys.
They stopped like donkeys to refuel.
They carried a heavy load.
They mistreated the donkeys.
The train looked sad and threadbare.
The train looked happy trotting back and forth.
The train is stubborn and reliable as a donkey.
They couldn’t make it go, no matter how hard they tried.
Personally, I prefer horses.
