Papa. "Who has put all these ink spots on my desk?"
Bobby. "Why, papa, those are not ink spots; it's a letter which I wrote to you."
Papa. "Jack, how did you get that lump on your forehead?"
Bobby. "Jack hit me with a stick."
Papa. "Did you strike him back?"
Bobby. "No."
Papa. "That was quite right."
Bobby. "Because I hit him first."
