I haven't actually lived in the States since I was 19 years old -- over twenty years, I can't remember anymore exactly :-)
The people who do it well gather at someone's house and have a lovely feast of farm-fresh goodies (including a farm-grown turkey). They talk and listen to music while the cousins and/or friends run around outside in the forest/countryside. There's an air of warmth, gratitude and love. A sense that this is a tradition that has been handed down generation to generation. There is a real sense of connection to the earth, to the previous generations, etc.
The people who do it poorly eat crap food in front of the television (yes, the whole meal), each talking over the other. Many watch the day's football game. I know, I gathered with a group of expats last year and it was just awful. Horrible.
But then, we don't own a television. Not sure if that's because we're half-French? ;-) I dunno. I know plenty in the States who don't own one.
In the States, then, you have Black Friday or whatever, the biggest shopping day of the year. Yuck.
But, having lived all over the world, I honestly can't say that all this isn't specific to Americans only. And having just arrived in the UK, I can't really say that there aren't plenty of people here who would do the telly Thanksgiving -- adding cigarettes to the mix. (sorry! but it seems true to me at the moment)
I'm with my girls today, dh is in Amsterdam and, of course, my family's in the States. I made pumpkin pie and pecan pie and none of the other dishes. We will set the table with candles and a warm-feeling tablecloth. We already talked about our gratitude at tea time but we will repeat the exercise over pie and read a a story called The Country Mouse's Thanksgiving.
