Startling Socks

Paula usually wear all black socks. Today, however, she was sitting in the sofa in front of the TV, suddenly stretching out a foot from the blanket, which had a pink sock with Mickey Mouse images on. Javier was so startled, he barked at the sock. It was not long before he realised there was no danger, but he still said he did not like being startled in this way. I understand him. Nobody expect us dogs to change the colours of the coats we usually wear, so why would humans do, at least on bodyparts where they usually never change colours.
