Winter Vampires

On the bus the other day and it was already getting dark at 4. I think vampires would THRIVE in the winter weather. I mean, the sun goes down early, a lot of people start to isolate because of how depressing the weather is, and all they would need to do is wear a winter coat and a scarf/hat/glasses and nobody would notice they were vampires. (I am freaking out about my final exams next week)
