My favorite season is somewhere between autumn and winter, or both if you like.
Autumn is the beginning of such a wonderful time. The smells are wonderful, the colors are beautiful, and my birthday is on it's way. Autumn is especially magical in New England (where they actually have a legitimate Autumn season). I also love the two Autumn holidays.
Winter is magic in it's own right (yes, especially in New England where they have a legitimate Winter season). Everyone is in the holiday spirit, the smells are (again) wonderful, and Christmas is coming! I SO love christmas.
I suppose both these holidays make me the happiest, the warmest, and I feel like the people around me are the most that way as well.
