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.

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.
