The Dog and His Reflection
A Dog found a piece of meat one day and while walking with it in his mouth near a stream, he saw another dog in the water with another piece of meat. He was not aware that it was his own reflection and not another dog. So, wishing to have the other meat, too, not satisfied with his own, he opened his mouth to grab it, but that moment, his meat fell into the water and it was carried away till he couldn’t see it any more. So, he remained hungry that day, because of his greed.
If you’re not content if what you have, you may lose everything in the end.
