once there was a mouse deer, went down to the river. he wanted to take a drink. but he knew crocodile might be waiting underwater to eat him. though all he saw was a floating log, he knew Crocodile looked like a log when he floated.
mouse deer had an idea. he said out loud, “if that log is really crocodile, it won’t talk. but if it’s really just a log, it will tell me.”
he listened. a rough voice said, “i’m really just a log.”
mouse deer laughed. “stupid crocodile! do you think a log can talk?”
moral of the story: think before you talk
