Actually, I really enjoy Christmas. While I don't get as many toys anymore (damn growing up!), it's still fun to check up with the family and play with the nephews' toys (though they're getting older now).
What I don't like about Christmas is how aggressively mercantile it's become. While out shopping for Halloween candy, I see displays with Christmas trees and Santa Claus. Thanksgiving gets no breathing room at all. It's primarily used to mark the day before "Black Friday", which is the day that people trample other people to death at Wal-Mart... I mean, the biggest shopping day of the year.
The worst part about this is that this is my first Christmas on the other side of the fence. As someone with something to sell, I'm going to have to find a way to tap all of this mercantile Christmas spirit while trying to make sure that I don't lose my personal love of Christmas.
