A Horse-soldier took great pains with his charger. As long as the war lasted, he looked upon him as his fellow-helper in all emergencies, and fed him carefully with hay and corn. When the war was over, he only allowed him chaff to eat, and made him carry heavy loads of wood, and subjected him to much slavish drudgery and ill-treatment. War, however, being again proclaimed, the Soldier put on his charger its military trappings, and mounted, being clad in his heavy coat of mail. The Horse fell down straightway under the weight, no longer equal to the burden, and said to his master: “You must now e’en go to the war on foot, for you have transformed me from a Horse into an Ass.”
He who slights his friends when they are not needed must not expect them to serve him when he needs them.
Aesop
