Why all the fuss over his hat?
Just after the Buffalo hunt, Dunbar gets very agitated when he sees someone else wearing his hat, which he lost during the hunt. I honestly don't understand his reaction. It seems very forced. He had already become friends with these people and they had come to accept him as a friend as well. He had given them many gifts (cups, sugar, coffee) and just minutes before he gifted his coat to "Wind in his Hair". So why was he so angry when someone else was wearing his hat?
He could have been cool about it and just said something like, "That's my hat. It's ok, you keep it. It looks good on you!".
