As in a documentary

ok, it is not a great picture, but when I processed it I thought that this blip reminds me of an old documentary about a happy life of someone before a great disastrous event. I don't know how to explain this: but have you ever seen, for example, a documentary about an earthquake? Well, it starts with a tracking shot of images of happy people walking in the street, talking to each other and then suddenly something happens. Well, I hope that nothing will happen (they are my friends and my boyfriend) but this photo brings back these old memories.
