It was cold in Pittsburgh today. But the high in Toronto was 12. The low was zero. Zero. I don't have any idea how I survived my two winters in Toronto. I know for certain that I wore a lot of sweaters. Occasionally even a very nice and terribly warm Icelandic sweater. Do you remember those? Well, I had one in high school. Interestingly, I was never much of a sweater wearer after high school. In fact, I don't wear them now.
