A man in Africa proposed a game to a group of children that were around.  He placed a basquet full of fruits next to a tree and told the kids that the first one to run and get there would win the basquet with all the fruits inside.

The man, surprised by their action, asked them why had they run all together if only one could win all the fruits. They answered:  "How can only one enjoy eating all the fruits if the rest were sad?"
