Even in the days when we were having a hard time making ends meet or weren’t sure where our relationship was going, we knew that when it came down to it, these disagreements did not even compare to the love we shared between sisters. I am so glad that life has brought us back
31. When we were kids, you were always the ‘cool’ sister. You had an awesome car, the best boyfriend and you seemed to like me more than anyone else. As we grew older, life got harder and things got in the way of being friends. For a while we drifted apart but now I am so happy that have you back in my life. You have become one of my dearest friends and I wouldn’t be where I am today without your love and support.
32. You are my sister by blood and my friend by choice. I thank God for you every day, for every laugh, for every happy memory. You have brought me as much joy as you have pain in your life….not sure if that’s a good thing but you know what I mean right? I just wanted to thank you for always being there and being so sweet to me. For taking care of me when I have been sick or stressed out. I love you and am so happy.
33. You are one of my best friends and the sister I never had. I couldn’t ask for a better person to come into my life and bring me laughter and love. We were two kids when we met, but now almost three decades later we are still best friends! Happy 30th wedding anniversary sister!
34. We have made it to our 30th anniversary and we couldn’t have done it without each other. I love you with all my heart. You have helped me through the good and bad times and have always been there for me. We will keep on growing old together, but we won’t grow apart.
35. Dear Sister, did you know it’s been 30 years since we first met? And here we are, together again and just as happy as could be. On our wedding day I’m sure we had a little premonition of how much we would change over the next 30 years of life. Now that I think back on it, we were both such different people then; more unruly, more independent and perhaps even less mature. Has that happened? Well, a few grey
36. There’s no one in this world that could ever be like you. There is no one who knows me as well as you do. There is no one I would rather celebrate 30 years of marriage with than with you. You are the love of my life, my best friend, my soul mate. I love you more than you could ever know.
