I am so lucky to have you as a sister-in-law. Thank you for always treating me like a friend, rather than as an in-law. Happy birthday!
In you, I found the most fabulous sister and greatest friend possible. Happy birthday, my dear sister-in-law!
You’re so much more than just a sister-in-law to me! I hope you have the happiest birthday, my true sister!
I couldn’t be more thankful to have a sweet sister-in-law like you. You truly are a very special godsend....
Here’s to a fab sister-in-law, hoping you have the most wonderful birthday ever!
