Once a farmer bought a well from his neighbor. After buying well next day when farmer went to take water from well, his cunning neighbor refused him to take water from well saying, "I sold you well, not the water..!!"Distraught farmer didn't know what to do. So, he went to emperor with his problem and told him about situation. Emperor asked him to bring his neighbor with him to court. Next day when neighbor came to court, emperor asked him, "Why are you not letting him use water from the well?"Neighbor replied, "Your majesty, I sold him well not the water.. so why should I let him use water from it??"Emperor replied, "That sounds fine.. but if you say that you sold just well and water is your then you have no business keeping your water in his well.so, remove water or you it up all immediately and if not then water will also belong to the owner of the well."Neighbor realized this mistake and apologized and left.
