Now that I think about it, it was the same guy who caught me both times. He stood there eyeballing me like one of those dogs trained to sense when someone's about to pass out or have a seizure (sorry - I couldn't think of a better way to say that). A split second before I went legless, he grabbed me. He also taught me how to fight like an Army Ranger. He'd show me some things and then tell me to attack him. I remember being on his back at one point pushing on his carotid artery and him basically shouting that no no no he didn't feel faint yet and to try harder. That was hysterical. He's so big and I'm a sneeze.
He was a really good friend. I should mail him a big pile of cake.
