It's the tenth anniversary of my sister's marriage. How can I bless her? Short message form

Sister: Ten years have passed. How time flies. Ten years ago, when you and your brother-in-law walked into the marriage hall hand in hand, I sincerely blessed you; In ten years, when you and your brother-in-law built their own small home together, I felt happy for you; Now that your marriage has been going on for ten years, I have nothing to give you. I just want to send two most sincere words: I wish my sister a happier life! Thank my sister and brother-in-law for taking care of me for ten years! thank you
