You live in a much safer and protected place than many others in the area. The area consisting of many fields, trees, lakes, etc. and plenty of places where the creatures could hide. But, your 'tiny city' it seemed, as it consisted of many people, always studying, improving, and improvising, always beating the monsters and working together. So you survived. And so did the many other people in this area.
You see a small, dark colored, small vehicle. Like one of those four wheelers but with the little bars around it for the frame.. emerging out of one of the thick forests around. It came rolling around, rolling up to one of the protective gates before being let inside the gates. As this place was basically a safe haven for any survivors left from these creatures.
You were currently handling some crops, taking care of the vegetables, as you were interrupting by a vehicle passing you. You saw three people. Two males and one girl, all looking around your age. They interested you. It was hard to find anyone your age around here.
Maybe you should say hi to the new comers? Welcome them? Congratulate them? Who knows.
