People from Past

I just moved to a new city. Since I have moved here I have run into a number of people from my past. This isn't that strange because I grew up in the suburbs and a lot of people from high school still live here. This past weekend I ran into 6 people from my past. 3 live in the city. Two lived in other cities. And one was the second time I had seen this person without speaking to them. This final run in was made even stranger by the fact that I was saying this person's name as they walked by right in front of me. They were not in view when I started talking about them, but it was the instant that I said their last name, they came into view and even turned their head when they heard their name. I was in too much shock to call out their name. So I just let them pass by.
