The Bull and the Goat
A Bull, escaping from a Lion, entered a cave, which some shepherds had lately occupied. A He-goat was left in it, who sharply attacked him with his horns. The Bull quietly addressed him—"Butt away as much as you will. I have no fear of you, but of the Lion. Let that monster once go, and I will soon let you know what is the respective strength of a Goat and a Bull."
It shows an evil disposition to take advantage of a friend in distress.
