Wedding Anniversary Letter to Brother-In-Law

Dearest (name of your brother-in-law),

You ran off with my sister’s heart and made her your own. You look after her and place my sister in your heart.  You look exemplary when you stand with your better half. I am blessed to have you as my family member. The care and adore, you share throughout the days make you both a charming couple of love, not for this very day, but forever. Happy Anniversary to the stunning couple !!

A gorgeous and dreamy pair with mountains of love. May you always continue to be like that. Inevitably try to perpetuate a cheerful family. Always look after each other and live with pleasure.

Having a perfect courtship doesn’t signify that you both are perfect. It expresses you can affirm each other’s flaws. Good and bad artifacts are part of life. All the time tackle it with a smile and forbearance. I believe you can face every bit of strenuousness. 

 It is verifiable that God brought you two hitherto each other, but the affection makes your bonding brawny. You both rejoice in your life by taking affliction and giving smiles. The victory of your marriage lies in your way of living. A long way you have crossed, but many are yet to accomplish.

You share a love tale with many shades of colors that are loveliest among all; it has jubilation, tears, care, and love. The story is not yet finished, and I hope it never ends in your life.

I  love you both.

Yours loving

On this special day, I pray to the Almighty to give you happiness, joy, prosperity, and good health. May you celebrate many more decades of glee.

Another year has gone by and a little less hair on your head but a whole lot of love for you in my heart. On a lighter note, sometimes I wonder, if I had a brother like you, my childhood would have been double fun with you and your sister. Whenever I needed a companion in good and bad times, you were always the guiding light.

I hope your sister has planned a grand celebration for you to make this day more special with lovable moments to cherish forever. The love and care that you share with me are valuable to me and I want them to grow stronger with age. 

Happy birth anniversary to your best brother-in-law. You are a true inspiration. Roses are red; the sky is blue, oh my dear brother-in-law, I love you. Miss you.
