Goodbye, Jack. You have been a sweet, wonderful, loyal horse and friend. I love when you rub your forehead up and down on my palm because you are happy to see me and because you think it feels nice. I love you and will miss you so much. I know you are in pain and life is not fun anymore, and letting you go is the kindest thing I can do; but it's so difficult because of how kind, trusting, and loving you have been to me.
