One person is wearing a green shirt while sleeping on the sidewalk while another person wearing black pants is sleeping on the stairs.
A couple of homeless men are trying to catch a few minutes of sleep before the police chase them away.
The people could be any gender, not necessarily men. The police might not chase them away just because they are sleeping outside.
