I know you by your foot steps on the stairs

Have you ever paid attention to the sound of a person's gait?  Some sound confident, others purposeful, still others walk so softly that they are nearly right behind you before you hear them.  Then there are those with a spring in their step as if their feet are always dancing to a tune that only they can hear. I remember learning about what makes us individuals when my kids were very young and one of the things that is unique to us is our gait.  The way we walk is the signature of our feet.  [Being a little more observant these days in a place that is not my own.]
