Grandpas and granddaughters are a winning combination. Wish your sweet grandpa a happy birthday with a special birthday card. Grandpas don't ask for tokens of love. They keep on loving no matter what. That's why it's so important to send a heartfelt birthday message on your grandpa's birthday. It might be one of the few times a year you can tell your grandpa just how terrific he is to you and how lucky you feel to have him in your life!
