The Thanks of Giving!

It's been awhile, Sleep is not going well, but its progress, I'll see how it goes by the end of next week. Now to your thoughts with mlp, if we celebrate "Thanksgiving", what do they celebrate? There has to be something cause there's always something similar to our holidays, I may have either forgotten it or this was never said in the show. But I never got further than halfway of Season 5. Just some brain food. I don't much on my mind so I'll just be going now, but remember to comment on this, if it doesn't exist in the show, what are some good fan Ideas?
