premise: A group of people sitting around on a couch, one holding a cat. hypothesis: There are a group of people hanging out on a Friday night.
neutral: People sitting on a couch are not necessarily hanging out. They could be sitting on the couch in a waiting room. It does not follow that a group of people on a couch are there on a Friday night. People can sit together on a couch any day of the week and any time of day.
