The fog's so thick you could cut it with a knife

I took this photo in Copenhagen, Denmark. The city was enveloped in a night fog. It was freezing night. The fog was so thick you could cut it with a knife. Back when I was in Barcelona, Spain, I bought a purple winter coat. There were two reasons. The reason one was night time temperature. It was a bit colder than I expected. The reason two was I just wanted to buy something special as a memento of the very pleasant days in Spain. The coat was quite thicker than other my jackets and came in handy in Copenhagen, Denmark as well. Lucky me.
