Apparently he was nearly involved in an accident because of snow. That being said, I got stuck on a flooded bus when I was 11 and I don't hate rain. I also had to walk home without a coat, in shorts, during a thunderstorm, when I was about 8, along with my sister and cousin, and I still love storms.
Meh. Like you said, each to their own - but going from loving snow to actively despising it because of one little incident seems rather unusual to me.
Anyway - last winter certainly was very sunny here. December 2010 was also very sunny if I recall. Winter 2012/2013 was not - the opposite in fact.
