A co-worker told me that she can tell who is walking in the hallway without looking based on the way the person walks. I was like, no way! So we did a test...she'll close her eyes and predict who would pass her door. She was right every time! Wow!
Apparently I flop my flip-flop shoes loudly. No wonder she always knew how to grab me when I got closer to her room to ask me a question or something. LOL
I don't always know who walking down hallway but I can feel foot stomps and have a good idea depending on how hard they feel.
