"I can guess who somebody is by listening to their footsteps and walk, a skill amplified by my particularly sensitive hearing.
Everyone walks in just an ever so slightly different way from each other. There's an odd cadence and pitch unique to everyone's walk. If you wear the same pair of shoes around me for too long, I'll be able to tell if you're close by if you take even just two or three steps.
I realized I had this skill in high school. I had a slightly suspicious friend who enjoyed proving his pickpocketing and slight of hand skills by handing you things he took from your pocket. His first attempt and success on me was his last.
