Snow

During the 'deep freeze' across Europe Germany was hit the worse. It was often blizzard conditions. You'd wake up in the morning and a couple more inches of snow would have fallen over night. It wasn't just snow that was falling though, we saw dozens of people slipping on the icy pavements. I find that human beings seem to have a default reaction for that situation. You slip, yo quickly get your bearings, you look around to make sure no-one saw, you get up and walk off pretending it didn't hurt. Failing that, you can turn it into a sweet-ass dance.
