Well, two weeks ago, the following happened to me: I was driving to work and at an intersection, I noticed a couple of elderly women trying to help an elderly gentleman on the ground. I pulled over and saw that the man, in attempting to slide from his wheelchair into the passenger side of a car, had fallen onto the pavement. Because I'm not trained in moving disabled people (it's harder than it looks, and not easy to get into a good lifting position), in lifting him into his wheelchair--I threw my back out! So while I was glad that I was able to help, I limped away not very happy that I had screwed up my back in the process. The worst part was that I had a triathlon two days later. I still managed to do it, but kind of lackluster, and my back is still not right.
Later that day, after finishing a swim workout, an autistic man who is often at the pool was running around the locker room (naked), in a panic because he couldn't find his stuff. He was opening all the lockers and shrieking. So I helped him look through all the lockers to see where his clothes might be. Finally, we found his stuff--in the very last locker, of course.
