I hate Thanksgiving. I love the idea behind it - I really appreciate a day that claims to be about acknowledging the good things that people have. Very zen or something.
But in practice, it's just a day that forces familial responsibility on me and makes it lose its meaning. I get a much warmer sense of family bonding if I spend time with them on a day where it's not socially required.
Additionally, traditional Thanksgiving food is unhealthy and overeating is encouraged. I -never- enjoy these things.
This year is especially heinous as I'm in Japan, so my foreigner co-workers all want me to hang out and eat crappy thanksgiving food with -them-. So not only will I be spending the day with non-family who I don't particularly care for, I'll have to eat their nauseating thanksgiving food and praise them for it.
