Warm is cold

I recall perfectly the weather report for today - sunny and high of 80. Ok, as of this morning's paper, high of 78. I am, of course, in my shorts; however, my thermometer has not risen above 70, and there is a rather cold wind blowing. Once again, check what I'm wearing (shorts or long pants) and then rush back to your closet and dress in the opposite. Will I never learn?

Of course, I could just go back upstairs and put on my long pants, but would be the adventure (or the story, for that matter)in that?
