I prefer cold. I love the ice, the snow and the comfort of the freeze. It is so refreshing. Hot is terrible for me. I hatez it! You can take off layers but there is a limit, whereas with cold, you can put on as many layers as you want. if you look at the Superhuman: Revenge of Azure, my character is Desu Ka, a cold loving superhuman with Ice/Snow manipulation. *shameless advertising* And cold is just so...adaptable, I suppose. I lovez the cold!
I like the cold, and I must say that i'm a fan of the AC.
I still have mine in my window even though it's 30-50 degrees out. I love my room being cold, and I need an AC or fan because my room is above the kitchen. Whenever someone's cooking, it's unbearable in here.
