Dear [recipient's name]:
You, Grandpa, are the best Grandpa ever!! We have made so many fun memories together-going on trips to the beach and mountains, making ice cream, growing the garden, and reading books. I love to hear all your funny and interesting stories about when you were growing up too. When I grow up, I want to be just like you.
Thank you for your love and for all the time you spend with me. See you again soon!
Love,
[Signature]
