Well, I was so rattled by this afternoon's experience that I left my bag with my swimsuit, goggles and other stuff in the locker room of my club. I called when I got home and realized my error, but no one there can seem to find it.
It is interesting that when I am in the midst of some sort of crisis event I remain utterly calm. When I was a lifeguard, I frequently had to deal with injured people, sometimes severe injuries. I was always calm and in command. But afterward I would be shaking. That's what happened today. When I got on the subway to go swimming I was quite shaken up. Only while I was swimming was my mind blank.
