What do you say your sister-in-law is in hospital?

Warm words from my sister to my sister-in-law: Hello, dear brother, it is my great honor that you can accept my brother and become my sister-in-law. This is a great event in our family. You can come to our house and get up early with our family. Your arrival will make our family happier. I hope you can integrate into our big family as soon as possible. Our relatives are very enthusiastic and can care about each other. If you have something, just say it.
