My sister and myself and one of our friends were walking from another friend's house back to my parents place one Friday night. We live in a small Midwestern town, in the country, really. The road we're on is flanked by woods on one side and a cornfield on the other. There aren't any businesses, very few houses, and even fewer cars on this road.
We're all talking and laughing and enjoying each other's company when we see a man walking in our direction but on the other side of the road. We , at least I, don't give him more than a passing glance as we walk past. However, just a few moments later, my sister looks behind us and mumbles "oh, shit." I look behind us, too, and see the guy we just passed had turned around and was now walking in the same direction of us. I watch as he crosses the street and is now on the same side of the street as us, following behind us.
