I am grateful for your willingness to keep a healthy relationship not just between us but also to all of your in-laws. I respect and adore you for that. To my great father-in-law, happiest birthday to you!

By relation, you are my father-in-law, but for me, you are my big supporter and a good caretaker among all in-laws.

Today is one of the happiest days of my life because my granddad just turned 80! Happy birthday grandpa, may each and every single day of your life be filled with happy events and lots of blessings, too!

Today is a good day to express how grateful I am to have a wonderful father-in-law who’s much cooler than I am but always makes me feel that I am just like he is in every aspect. Happy Birthday Father-in-law!

Here’s wishing you a very happy birthday, my grandpa. Thank you for all the great things you did not just for me but also for the entire family. I thank God for your existence and I hope He will bless you with many more birthdays to come.

Granddad, I’m truly honored that you’ve bestowed your wisdom on me. Thank you for helping to secure my future. I really hope that your birthday will be as incredible as you are. Happy birthday!

Happy Birthday father in law, may this day be filled with cheer and good times, ones that will make you nostalgic over some time.

Thank you for everything that you do all year, couldn’t ask for a better father in law. Happy Birthday to you.

My dearest grandpa, I only wish you long life and more blessings from above. I wish you would live a life that is filled with great wonder and joy because that’s what you truly deserve. Happy birthday!

I am grateful to you for all the lessons and advice that you gave me. Thanks to you, I have become a really wise and courageous man who wants and will take care of your daughter. Happy holiday!

A cup of coffee with you every weekend equals a thousand hours worth of wisdom gained through life experience. Happy birthday grandpa.

Many things have changed over the years, but your love and care for me still remained long after I have entered your family. Best birthday wishes to you, father in law.

Wish you happy birthday daddy. No matter where I go, where I live, where i work, what I do. You hold me together in all situations. Wishing you on your birthday makes me to be with you.

There are two types of fathers-in-laws. The first type is those who behave like real fathers-in-law. The second type is those who act like real fathers.

I am a bit jealous of you because my kids love spending time with their grandpa more than they like hanging out with me. But I don’t mind because you are the best role model for them. Happy birthday, daddy-in-law.

You helped me to walk when I could hardly take a step as a baby. When you become old and fragile, you can count on me to do the same. Happy birthday grandpa.

When I was little I grabbed your finger to take my first baby steps. When you are old you can hold my hand to take your first wobbly steps. Happy birthday grandpa.

Just like how the beautiful grandfather clock is the pride of our living room, you are the pride of our lives. Happy birthday grandpa.

Grandpa, thank you for listening to me as I’ve attempted to sort things out between us. Thank you for accepting me for who I am and for still loving me despite of my shortcomings. Happy birthday!

The whiteness in your hair and cross wrinkles on your skin may be hide layers of your wisdom and knowledge, and it shows the depth of your experiences. Happy birthday to my wise father-in-law.

Happy birthday my dearest father in law. You do everything to save the family from any harm physically, emotionally, and spritually. Thank you and have a beautiful birthday.

Stay strong and positive for all your life. You are an inspirer and motivator. Now I know to what your son is like. Surprises are waiting for you. Great birthday!

I don’t think that calling you father-in-law would still be appropriate neither calling you by your name. I think I should call you dad. Right, Happy Birthday Daddy!

Ever since day one, my respect for you has always been the highest. You are one of the most remarkable people I have ever known and I thank God for that. Happy birthday, father-in-law!

Grandpa, please know that you only turn 70 once. So I hope you will enjoy your party to the fullest. Please know that you truly deserve all the happiness in the world. Happy birthday!

Thank God he gave me your daughter to be my wife. If not, I wouldn’t have the chance to have an awesome Father-in-law like you. Happy Bday Daddy!

Wishing you a fun-filled birthday that will take any of your stress and cares away, sit back and enjoy, make the most of it.

I’m so blessed to have a father-in-law who treats and cares for me like his own. You never treated me like I’m just your son-in-law. You loved me like I’m your own son. Happy Birthday and thank you so much dad!

My grandpa, I’m forever grateful for your presence in my life. Thank you for sharing me some inspiring stories. These stories are the reason why I am working so hard in life. I want that you’ll be proud of me someday. Happy birthday!

Happiest birthday to an amazing grandfather who just turned 60 today. Grandpa, no words can ever express how much you really mean to me. Thank you so much for sharing your precious life with the family.
