In the nearly 9 years I've been living in Southern California I've become a wimp when it comes to cold weather. I grew up in Salt Lake City and saw plenty of cold winters and enjoyed sledding and playing in the snow as a kid, and skiing when I got older. But it got to the point where I began dreading the cold earlier and earlier each fall. At the slightest hint of the end of summer I began to shiver. After we moved here I found it amusing that some people wore jackets (or even heavy winter coats) during the "cooler" months of the year, but now I've become one of them. And if I'm not mistaken, this year has been unusually cool. Of course, things could always be worse.
As for me, I think I'll put on a jacket.
