Post apocalyptic world would be a mess. Trashes everywhere and homes broken into. Less old, sick, and little kids around. Mostly only abled bodies left because the weak die first. People would avoid each other like the plague. Among the people, there are predators that want to take what you have. To navigate safely, you have to travel at night time with only the lights from the moon to draw less attention. Most likely have to sneak from place to place to avoid detection. I imagine most people would have their groups or communities to live with. Some loner type people out for only themselves.
The people I want to have around are people that I can trust completely, like family. I might keep useful people around for a time being as long as it serves my purpose. By useful, I’m thinking farmers or people in a community that I can use. As cruel as this may sound, I’m not above throwing people under the bus when it’s convenient for me. I think people wouldn’t hesitate to backstab me, so might as well do them in before I get done in myself.
