What's in a name?

For several yrs. now I have teased my mom and dad about becoming older and am always calling them Grandma and Grandpa. :)So of course we call them that all the time now. They come over and see the kids often and we make several trips to Borger to spend time with them. Cade loves playing with them, of course being a boy he seems to favor my dad. He loves letting Grandpa pull him in the wagon or wrestle on the bed. If we go out to eat and he gets bored Grandpa is the first to take him outside or walk him around the restaurant. Well the other day Cade started saying a new word. He said Papa. Now as a mother every new word completely melts my heart. However, when he said Papa for the first time the look on my dad's face was priceless. I know without a doubt by the smile on his face and the twinkle in his eyes his heart melted a lot more than mine did that day. It was a very sweet moment that we will cherish forever. Here is a pict. of Cade and his Papa.
