An ipod of whales beached themselves in Western Australia a couple of days ago. Aren't the people, the non paid ones, truly wonderful in their devotion to saving them. Most often they aren't terribly successful, but that never stops them.
When you have had a crap day, just remember, the world does not revolve around you. You will get over it. Get out and do something for someone or something that is thankless. You are not going to get an award, but you will feel better.
