The story is about Mallam Sile, a blind tea seller who went abroad in search of money to help his parents, but while he was doing that, his parents died. He didn't go to the funeral, but continued saving money. Everybody took advantage of him at his work, because he was blind, but he kept treating everyone with respect nevertheless. He is a romantic, sings songs about finding true love. He manages to save enough money to come back home and open a tea shop. He married, and his wife took great care of him, even beating a guy who didn't want to pay him his debt. After that incident, people started respecting him, and he thanked Allah for the good life he had, as well as a great wife.
Why is the sky blue?
The light that comes from the Sun is white. That white light is actually a mixture of all colors, but because they are mixed up we don’t see the separate colors just the white sunlight.
