I was working out at the gym today, and when I was changing in the locker room into my shorts to wear so I could lift weights (I had been swimming and thus was wearing swim trunks), this man who was probably in his late 50's or 60's had come up because his locker was next to mine, and he all of a sudden started saying these words that I couldn't even understand because they were mumbled and he very slowly kept patting me on the back... I just minded my own business, getting ready to do what I was going to do, and then was very happy to leave... It's gradually been bothering me less and less, but I found it really creepy and unsettling...
