One day in school, little Johnny asks the teacher,"Mrs. Roberts, when people do something wrong, they get punished. Right?""Yes, if you do bad things, I will punish you," Mrs. Roberts answers."Then, can I be punished for something I didn't do?" little Johnny looks nervous. Mrs. Roberts is shocked, uOf course not, Johnny. That would be very unfair." Little Johnny is relieved."That's great. Mrs. Roberts, sorry, I didn't finish my homework." Now Mrs. Roberts is angry.
