You are like a soft breeze in a warm summer day – gentle and cool. Wonderful bday, sister in law!
It boggles my mind that there are people who don’t like their sister-in-law. But they must not be blessed with a considerate, loving, and supremely likable sister-in-law like I am. I am grateful that you are a part of my family, and I hope that you have a marvelous birthday.
I am so thankful that you found your way not just into our family, but into our hearts as well. You always bring a smile to our faces, and we are blessed to have you in our lives.
Stay kind and gentle like the wind drifting softly through the meadow.Wonderful birthday, sis-in-law!
Sister-in-Law, you have made not only my brother extremely happy but me as well. You are an affectionate, endearing, and inspiring person that we are both lucky to have in our lives. May your birthday bring you nothing but satisfaction and wonder this year.
I’m beyond excited that I married your brother because having a sister has always been a dream of mine. May your birthday be full of excitement but your life full of tranquility.
I’m glad that you have become my sister-in-law because now Mom and Dad can harass you for grandbabies instead of me! You have my heartfelt gratitude and love. Happy birthday!
Thank you for giving me something that my parents never did: a sister. You mean so much to me and are an invaluable part of my life. May your birthday magical and bright.
Wonderful bday to you my amazing sister, you are the greatest gift that life gave to me after marriage.
No gift could ever compare to the one you have given me: family. Thank you for being an incredible wife, a marvelous mom, and a fantastic friend to me. Happy birthday!
I’m beyond lucky because not only do I have an amazing friend in my life, but I also get to have that friend as my sister-in-law. Win-win. May your birthday be as warm and bright as you are.
May your special day be full of astounding discoveries, magical moments, and lovely surprises. You deserve all these things and more. Happy birthday to an incredible woman: my sister-in-law.
Thank you for looking after my kids when my husband and I are going out on a Friday date night. I couldn’t imagine a world without you in my family. Best wishes to my beautiful sister-in-law. Best bday to you!
Sister-in-Law, I just wanted to take today to thank you for fulfilling a dream I have had since childhood: having a sister. I am so happy that we are close, and I hope we always stay that way.
When my older brother married you, I was worried he wouldn’t have time for me anymore. But I couldn’t have been more wrong. In fact, we are closer than ever, and instead of losing my brother, I have gained a new friend. Thank you, and happy birthday Sister-in-Law!
A sister-in-law is a wonderful addition to any family. Not only you get an extra sister, but you also have someone to gossip with the latest trend and just about anything! Have a wonderful birthday, my sister-in-law!
Sister-in-Law, if you ever need someone to confide in, please turn to me. Especially if it concerns my brother, because I need all the dirt I can get on him! Just kidding. But know that I will always support and love you as if you were my biological sister.
I was so worried about how you would impact my brother’s life that I was blind to how you would impact my own life. You have made such a deep and meaningful impression on both of us, and I am fortunate beyond belief to be related to such a remarkable woman.
I’ve always criticized my baby brother’s choice in women, but when he met you, I was elated. I knew right away you were an extraordinary person, and I am so glad that he somehow tricked you into marrying him! I hope your birthday is as joyous and sweet as you are.
When I got married I feel like I won the jackpot with having you as my sister. Happy birthday I love you so much.
In times of emotional whirlwinds, you are there as my shoulder to cry on. In times of trouble, you are there to back me up. Thank you for not only being my-sister-in law, but also a friend that I can always count on. Happy birthday!
Looking forward to more chats over Starbucks with you, more shopping sprees until our feet hurts and more hair or nail sessions at the salon with you. May we have more dates together in the future! Wonderful birthday, my sister-in-law!
Not only you are like a sister to me, but you are also a wonderful adviser and best friend. Best bday, sister-in-law!
Thank you for making our family stronger by being in it. You are a loving wife and an amazing friend. I am so blessed to have such a genuine and sweet person as a sister-in-law.
I couldn’t have asked for a better sister-in-law, because you are calm, cool, and captivating. How my brother managed to trick you into marrying him is still a mystery to me, but I am glad you fell for whatever it was! Happy birthday to my remarkable sister-in-law!
Sister-in-Law, I want you to keep in mind that my brother inherited all his good traits from me. So you have me to thank for him being so awesome. Just keep that in mind when you are divvying up your birthday cake is all I am saying. Happy birthday!
Wishing you the most magnificent, amazing, incredible, sensational, talked-about and brilliant B-Day! You deserve it!
Now that I have a splendid sister-in-law like you, my brother doesn’t have to worry about spoiling me. You have taken over that job, and I must say you are doing it phenomenally. Thank you for showering me with your love, and I hope that you feel just as loved on your big day.
The best decision that my brother has ever made is by having you in his life. You guided, tolerated and loved him in spite of all. I will forever grateful for that. Happy birthday to such a lovely person such as you, my sister-in-law!
Sister-in-Law, from one mom to another: I’m impressed. You manage to get everything done and look fabulous while doing it. Please tell me your secret! May your birthday be as perfect as you are. Happy birthday to my impeccable sister-in-law!
