Tom likes to talk much but his father doesn't want him to speak when they have their meals.One day,when they have supper,Tom wants to say something,but he doesn't say.His father sees it and asks him,"Well,my boy.What's it?""Are flies   good to eat,Father?"asks Tom."No,"says his father,"Why do you ask that?""You have one on your food and you have swallowed   it." Why doesn't Tom tell his father there is a fly on his father's food?
Because he 1ikes to see his father eat a fly. Because his father likes to eat flies. Because his father doesn't let him speak at that time. Because he doesn't see the fly on the food.
