Hey, Grandpa!
I hope this day finds you well, energetic and sparkling as usual.
I hope you get the chance to celebrate with all your family, and most of all with your angel, Michael (even if only on the phone).
My gift for you isn't a big gift... It ain't much, I know. It's just a small thought, but you know it's a token of my affection and dedication to you and comes directly from my heart. You already know how special you are to me, but I'll never miss the chance to tell you, because it's always good to say "I love you".
