A horse was pasturing in the same place he had always pastured when an old cow approached him and told him:
"The grass from that meadow over there are fresher and greener"
"if that's so, why are you here, then, and not there?"
"I don't know, I just wanted to let you know."
"But that's not your duty."
"I know, but neither it is to keep and enjoy something so good all by myself."
The end.
