Once upon a time a bug named Mandavisarpini made for itself a small home in the folds of the milk-white sheets of linen spread on the king's ornamental bed. One day, the bug saw a flea drifting into the king's bedroom and told the flea that he had come to a wrong place and asked him to leave before somebody noticed him. But the flea didít give an ear to his advice and keep on insisting to taste the royal blood of king.
The bug told him, "oh, flea, I suck the blood of the king when he is fast asleep. You are impatient. You have to wait till I finish my job. After me, you can have your fill." The flea agreed.
Meanwhile, the king entered his bedroom to sleep. But the impatient flea began feasting on the king's blood even before he went to sleep. Stung by his bite, the king rose from his bed and asked his servants to look for what was in the bed that caused him discomfort. The king's men pulled the linen off the bed and examined it closely. Before they could him, the flea sneaked into a recess of the bed. The servants found the poor bug and killed him at once.
One should not have friendship with strangers.
