Frank liked to wear headphones when taking tests. The headphones were inspected and approved by his instructors as being the type that only blocked noises. He said they helped him concentrate. Julie sat near Frank in class and was convinced in her own mind that he was somehow using the headphones to cheat. When their papers were returned after one test, Julie saw that she had a perfect score and noticed Frank's paper showed he had missed two questions. She leaned over toward him, showed him her paper and said, "Ha. I made a 100, and I didn't cheat like you did." Does Frank have a libel case? Why?
