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.
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!
Sister-in-Law, your birthday is a truly momentous occasion. Not only is it a celebration of the day you were born, but it is a yearly reminder that you deigned to say “yes” to my baby brother and became a member of our family. Thank you for keeping him sane and for treating me as a sister.
I always wondered how my husband came by his genuine, loving, and respectful ways, and now I know: he grew up with an amazing older sister who taught him to treat women with respect. Thank you, and happy birthday!
Happy birthday to the only woman brave enough to marry my brother! You are my hero. May your birthday delight you and your joy be immeasurable this year.

Sister-in-Law, I was trying to think of the perfect gift to give you for your birthday, but then I realized that you already have the best gift: me as your brother-in-law. I couldn’t possibly top that, so I went for chocolate cake instead!
Have a lovely day with great memories my caring, and supportive sister-in-law.
I adore you as a person, confide in you as a friend, and love you as a sister. You make my life better with your presence, and I hope that you always feel surrounded by peace and love.
When my brother got married, it was such a welcome surprise to find out his wife had a sister. This way I got, not one, but two new sisters! Happy birthday to my superb sister-in-law!
Family get-togethers are more fun when you are around. I always look forward on catching up with you whether it is the latest fashion or just about anything that we are up too lately. Happy bday, sis! May you a great and fun birthday!
