Someone sent me a page out of a newspaper, and as I took it out of the envelope I thought I was busted. There was a full-page article on the short-tailed weasel, a burrowing mammal local to my correspondant's area. Its fur is brown in the summer and white in the winter, so it would make a poor pet. No matter what colour furniture and carpets you had, you wouldn't be able to hide the shedding in spring AND fall. Then I turned the page over to discover the article I had been intended to read. It was about an airline pilot who is probably also white in the winter and brown in the summer, like many caucasian Canadians.
