premise: A man in plaid pants and a vest is speaking into a microphone to a group of people, who do n't appear to be looking at him.
hypothesis: The man is looking unhappy.
explanation_1: speaking doesn't mean he is unhappy.
explanation_2: If no one is looking at a man who is speaking to a group of people, it doesn't necessarily mean he is unhappy.
explanation_3: A man speaking to no one doesn't really imply that he is unhappy.
