I learned today that after walking 10k (for the San Francisco Aids Walk) and finally driving home in your car, that it's almost impossible to stand again.
Oh, and the old adage about asking someone something about themselves to get the conversation rolling: Yes it's true; people love to talk about themselves - especially actors. But they don't return the questions to keep it going. So, when they are done, the conversation comes to a halt. A little odd when you're walking next to each other in a 10k walk, but oh well.
