It's winter?? Since when?

So I was just chilling in the eagle's nest last night when a friend of mine looked at my shoes and then looked at me like i was crazy. At the time I wasn't sure what was going on but today I realized that she was making fun of the fact that I was wearing flip flops in the middle of winter. It was 50 degrees out last night! who cares if I was wearing flip flops? At least I wasn't running around in shorts and a t-shirt (which I do quite often when it's snowing).
