Because, for some unfathomable reason the whole country grinds to a halt when we get a foot of snow on the ground.
An example being, last night we has said foot of snow, and when I trudged to nursery to drop off my little one there before heading to work I was told they were closing as she was the only child that had turned up!!! I had to return home with her and phone up my very pi$$ed off boss and tell him that I couldn't come in as I had no babysitter.
We all knew the snow was coming but everyone seem gobsmacked when it actually arrived.
Thank God we don't live in say Sweden for example, we'd be goosed.
