We will never get tired of celebrating birthdays. That's someone's special day when they become one year wiser, better, and hopefully happier. When it's your father's birthday, instead of simply saying, for example: "happy 76th birthday, dad", you should greet him and show him how grateful you are for everything that he has given to you. A birthday message for a father should really be something special. You can tell him, or you can write your message down on a beautiful or funny birthday card. The choice is yours. With these 40 messages, you will be able to wish a happy birthday to your dad in the most creative and touching way.
