One day as a teacher is walking into the classroom,he hears a low voice,"Here is the teacher.I'm sure the unfair fellow is going to talk about putting in commas." It is Billy's voice.He is talking with the boy next to him.The teacher isn't angry.He says nothing about it,but begins to talk about putting in commas.And then he writes a sentence on the blackboard,"Billy says the teacher is an unfair fellow." The class laughs and Billy's face turns red."Now," says the teacher,"I'll show you how important commas are." He puts two commas into the sentence and then reads,"Billy,says the teacher,is an unfair fellow."
