The Oxen and the Axle-Trees

A HEAVY WAGON was being dragged along a country lane by a team of
Oxen. The Axle-trees groaned and creaked terribly; whereupon the
Oxen, turning round, thus addressed the wheels: "Hullo there! why
do you make so much noise? We bear all the labour, and we, not
you, ought to cry out."

Those who suffer most cry out the least.
