well, thinking seriously about it, neither. what i like is when the season changes, like when in winter you see the first flowers coming out of the ground, you see a warmer sun in the sky, and nature seems to slowly wakeup from her winter sleep.
i tend to prefer winter because my foundation stays put and i'm not covered with excess oil and sweat, but i also like summer, the sun makes my hair shine while during winter it's just dark.
