What is wrong with me??

Today I walked to class. Not unusual, until I noticed the girl walking next to me. She was wearing a tank top, mini skirt and flip flops. In contrast, I was wearing shoes and socks, jeans, and a hoodie sweatshirt over a 3/4 sleeve t-shirt. Um.... hello? Is one of us in the wrong climate?? I know I get cold easily but is this even normal?
