Once, there was an ox named Spaci who lived in the house of his master. Spaci used to do the work of carrying loads every day. He had a friend, a flea who lived in a nearby tree. The flea noticed him carrying tons of loads every day. One day, the flea called Spaci, and boasted how exhausting life he lived. In spite of being a smaller creature, he lived without any burden.
Then Spaci replied, “I am not an ungrateful animal; I am loved and well cared for what I do. Besides, my master often pats my shoulders and head for the hard work that I do for him.” “Oh, that sounds very good, but I can’t survive like that. You see, one little pat from him will kill me instead,” replied the flea. Saying these words he flew away.
