Well, that's not a terribly nice question to ask, but I suppose it's fair. If someone want me to teach them something, maybe like spitting beans at ghosts, I should want to know why it is they want me to teach it to them. Especially for something as silly as that! I should think it would be rather obvious, don't you? Spitting beans at ghosts, or even at people, isn't exactly hard.
