Do I walk funny??

Last night I was walking toward an elevator after visiting a family member in the hospital.  As I approached the elevator there was a woman also waiting for the elevator to arrive.  A few seconds passed, then the woman turned toward me and asked if my name was Kyle?  When I said it was she then told me her name.  This was a woman whom I did not recognize at all, though once she told me who she was I did remember her.  The reason I didn't recognize her was due to the fact that the last time I saw her was 24 years ago.  We had been in a community play together, I played the character Roger from the Neil Simon play "Enter Laughing."
Once the name and the face were known to me, I did see that it obviously was the same person.  I asked how she was and she did the same, then I had to ask the question, how did she even know who I was?  24 years ago I was thinner, I had more hair on top of my head, and I did not wear eyeglasses.  Her answer was that she knew it was me by the way I was walking down the aisle toward the elevator.  I do admit that I have a little back and forth sway in my stride but was stunned that someone would remember that so many years later.  It turns out that she doesn't see up close so clearly and so she will remember something else about the person aside from their face to help identify who it is. For me it happened to be the way I walk. It is always fun to be remembered by someone who you have not seen for a long time but it would be nice to have someone say " As soon as I heard your voice I knew it was you" or that they just remembered your face and it had not changed after all those years.
I admit that I am not good with recalling people's names after  not seeing someone for a very long time, maybe I should start to remember the way a person walks to help me out with that.
