The first Thanksgiving was on 1621 the reason was that the Pilgrims were celebrating there harvest and survival from a long winter. Back then the first people who landed on the new world keeped dying they didn't have things like houses food or water they need to make that before winter came by the time they had houses up most of the people that came with them had died. So this is why the Pilgrims were celebrating Thanksgiving they had lived through the winter for the first time with not that many deaths. Later in the years Thanksgiving became a Holiday for lots of people to celebrate with all there family. Not all of us celebrate this day people from the U.K don't celebrate this day for some reason maybe because is appended over here in the new world. One thing am thankful for is for having all i need in life. Another thing is be able to get my grades up. Another is getting to see all and i mean ALL of my family and that's a lot of people and that's it am happy for nothing alse.
