explanation_2: Just because three people wearing black chatting on a street corner, doesn't mean they are waiting for the bus.
explanation_3: Just because a group of people are chatting doesn't mean that they're waiting for something. Being at a street corner doesn't mean that they're expecting to get on a bus.
