Dad, you were my first love. I always wanted to go to daddy´s house. We would go to the pool. Hang out with grandma and grandpa in the backyard. I would watch you and Lexi riding dirt bikes in the field out back. Still can´t forget when I got on the bike I drove straight into the house. You knew I wasn´t made for the dirt bikes life. So you downloaded music on your Xbox so I could sing and dance any time I wanted. I remember you would take us to the store to get all the best snacks, go on back road drives listening to music. I miss annoying you. I miss your warm hugs. I miss the sloppy kisses on my forehead or cheek. Sissy misses you more than you know. My kids will know your name. They will know your story. And they will know your HEART. time is precious and I wish I knew that before it was too late. I love you dad. I love you so much.
Ride the clouds, sit and have a smoke with grandpa and make sure you give Heidi so may lovins. She´s been waiting for you
