The poem read: "Dear brother, my whole life is up rooted and changed and yet people expect me to be the same.

"But how do I go on like nothing has happened continue to look at life with joy and passion? People come and people go that's true I know. But some people you want to hold tight.

"Some people you want with you through every fight to help you feel that all is right.

"You always pushed me to be the best that I can be and for that I owe you an eternity. An eternity of gratitude, love and appreciation you showed me life was such a beautiful creation. I'll forever hold you in my heart, I know that we are not apart.

"I know that you are with me every step of the way I can hear you in my mind saying, 'Go on Gracie, this is your day!'"
