Boka and Khoka had climbed up a ladder to get on top of the roof. While they were fooling around on the roof, a strong wind blew and the ladder was knocked off.
Wondering how to get down, Boka said, "I have a suggestion. I can push you down. Then you can pick up the ladder and position it for me to come down."
Khoka said, "Don't try to be over-smart and don't you take me for a fool. I have a better suggestion. I will put my torchlight on, and you can climb down holding on to the beam of light."
Boka commented, "Do you think I am a fool? You will turn off the torchlight when I am mid-way there."
