Hang on

                  A man was climbing up a high cliff, and was almost to the top when he heard a noise that sounded like a snake. He thought, should I climb to the top and get bite by the snake and die, or should I just let go and fall to my death? ​    
                Back then they didn’t have the stuff that they have now for climbing, he was just using his hands and feet to climb up the Mt. top.
               After a few minutes he decided to take his chance with the snake. When he reached the top he didn’t see the snake, but he did see the wind blowing a bush, and that was what was making a noise like a hissing snake. The point is when you don’t know for sure about something, hang on, it may be only a bush making a noise, not a snake.
