I saw a show on TV a while ago that showed how these animal-safety-activist-superhero-people had saved a bunch of dogs from a house where they were supposedly being abused/malnourished, etc. Their plan was to take these dogs to a park and let them run around on the grass and bask in the warm sunlight—which was, I guess, something that these dogs had never experienced before. When they got to the park they opened the back doors of their animal-rescue-van and opened the kennels and they were expecting the dogs to just jump right out and run around and have a great time. Instead the dogs started pissing themselves and curling up in the rear of the kennels. After a long time one of the dogs was coaxed out of the van somehow and when its paws touched the green grass it didn't know what to do. It couldn't stand up. It just slumped down and laid there whimpering. My guess is that its paws were not used to the softness of the grass. They were probably used to hard concrete and chains and coldness. Eventually the dog gained some confidence and started walking around.
I have to go, but just one more thing: That one brave dog influenced all of the other dogs to jump out of the van and face the unknown. Maybe they thought the sun was going to kill them. Maybe they thought there was fire outside of the van. They had a lot to be afraid of, but they eventually faced it all and realized that all of the things that they thought were scary were actually good things that could make them happy. Anyway, I'm glad that I stayed up late and finished watching that show.
