It's a common trope in visual media to show something not actually related to the main story in order to set the scene nicely. The problem is, there's this thing called Law of Conservation of Detail. If something appears, if something is mentioned, it must surely have some importance.

Thus, if we were shown this random kid, it must have some importance. It wasn't the same as showing people walking on the street, or talking in a park, which are just setting the scene.
