Pumpkin Pie High

There is nothing like it, the pumpkin pie high! It could have been the 6 emptied wine bottles or the champagne but I like to think it's the creaminess of the pie. There is something that takes hold of our tongues on this holiday. I know what you are thinking, but in our family it's the opposite! Every year we end up with a few random visitors at our house and they must leave thinking they've just experienced a day with the Cleavers. We eat, drink, tell jokes, play pinball and eat some more. We never discuss the real issues going on in our lives. I guess we use Thanksgiving as an escape from our realities. Well, this year was a little different.
Since this is only my third post I guess I need to give a little background information. I have to give this info in small chunks because my life can be unbelievable when it's all summarized at once! My parents have been on the babyboomer rollercoaster: started as hippies, moved on to yuppies and now they are just so set in their ways it is ridiculous. Now that I am a parent I find myself struggling with my parents' point of view quite often.
Back to Thanksgiving- It was about 1pm and we were all sitting around discussing very neutral topics and my Mom brings up the whole friendly Pilgrim/Indian relationship, despite all of the evidence, she still believes this big friendly feast occurred. Here's where things get a little rocky. I ask her to please not teach my children stories that are not true. They aren't even old enough to question what this holiday is all about so I figure why even go into it? She then goes into this whole deal about how I always try to ruin things with the truth! How do I respond to that? In the spirit of our family, I get up and walk away. I want my kids to enjoy the holidays just as much as I did/do but I am so tired of history being so terribly misrepresented. What is your opinion on this? Will your kids think that the Pilgrims did nothing but kind acts towards the Natives they encountered? Will they know about the continuous disrespect of a people that were indigenous to a land that was taken from under their feet? I am kind of hoping that I can somehow teach my children about history without damaging their innocent little spirits! Any ideas?
