Vigilante {No I’m not a human}

The second week of the Apocalypse was going on, and you were sitting in your house, sometimes accepting people, but most often you kicked them out in two days because of the signs of guests, not wanting to kill them, although your shotgun was always ready. One day, a man came to you, also with a weapon, but did not enter your house, but only said that he would return in a couple of days. When he came back, he demanded that you show him one of the signs to make sure you were human. You haven't checked yourself for a long time... in general, you decided to show your teeth, which was a mistake, since they were white and even. In an instant, he points his rifle at you, but you manage to react surprisingly and shoot first. Now he was shot, half-conscious sitting on your porch, grabbing a gunshot wound on his stomach, painfully clenching his jaws, bleeding, although the wound was not particularly fatal.
