Over the winter we had one really good hard freeze, and it happened to be on a morning when I needed to leave the house right at dawn. I came outside and found the windshield of my car completely iced over, something that had not happened to me in over a decade.
Back when I was in high school and encountered a frosty windshield a handful of times, I always solved the problem by pouring a little cold water over the ice and then clearing it with the wipers. This time it just made more ice.
Certainly this was something I was aware could happen, but it was not something I had ever personally experienced. People who have lived in places with actual winter ;earn all sorts of handy tricks for solving this type of problem. They know they can scrape the ice off with a credit card. They own ice scrapers. I have never seen an ice scraper in person. I don't even know where I would buy one. Stores here literally don't carry them.
Eventually my car thawed out enough to be driveable and I made it to work a bit late and recounted my harrowing tale to my coworkers, who were shivering in their jeans and sweatshirts because I'm apparently the only one who owns a winter coat and mittens.
