Winter, easily. I'm very cranky now that it's spring and getting warm out. Hot weather makes me miserable, and so does bright light. I was really enjoying the whole thing where it was cold and dark out for a few months there. Now it's warm enough that I have to open my windows (instead of hanging blankets over them like in the winter, which is great for keeping it warm, keeping the sun out, and keeping noise out), and that means I have to hear kids running around outside and traffic going by that distracts me from whatever I'm trying to do. Is it next winter yet?
