This very same girl, with the very same shoelace hanging untied was walking right in front of me from parking lot up to my building on campus two days in a row. The second day I got out the camera and tried to take a picture of the untied shoe. It wasn't easy as she (and I) were walking very rapidly, with her talking on the phone all the way (same as the day before). So this isn't a very good, clear picture. I lowered the saturation on most of the picture except for the foot with untied shoe, to make it stand out more. Not a great example of photography, just a souvenir of this oddity.
