Indians vs. Pilgrims
There were the Indians... One day in the island & they began to see people coming... They were scared.
-We need to hide in because I think they are bad people, said an Indian
When the Pilgrims arrived, Indians were scared but the Pilgrims saw them & they started to hit and bother the Indians, the Indians were so pacific with the Pilgrims & let them stay there & they were friends & shared food.
So that is why Indians say THANKS!
