The Brits find Americans cheesy when it comes to Thanksgiving. Well, most do.
Why is that Sarah?
I can't really explain it but you have a very different way of expressing yourselves in general and have a kind of traditional culture without much history to it. The way you live your lives socially and everything!

Its just completely different.
And thats before having started on your accents.
Americans are a lot more extroverted then the British, you make something out of nothing, just to do things! Which is both a good and odd thing.
