A man in a red shirt is standing next to a woman in a blue dress. They are both holding hands and smiling at each other. A group of people dress up and participate in role playing games. They are not necessarily having a party. A person is walking down the street, wearing a red hat and carrying a bag. The person is not wearing a uniform. If I don't know if every citizen does or not but just you having lived in Houston you know what it's like out there, can we conclude that 'I know that none of them do that.'?
