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!

You are like a wild flower in a desert – rare and delicate.

I wish you fortune, treasure, and wealth this year for your big day, Sister-in-Law. You may have noticed a common theme with this wish, but I promise that it’s for a good reason. I really, really need you to buy my brother some common sense this year! Just kidding, and happy birthday!

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!

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.

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.
