the 10th anniversary of our marriage
We have just celebrated the 10th anniversary of our marriage.
We have just celebrated the 10th wedding anniversary.
A: Why did you prepare a candlelight dinner. Is there anything special to celebrate?
B: You won't forget what day it is, will you?
A: Of course. I remember it was on this very day last year that we tied the knot.
tie the knot表示“结婚；永结同心”，比如：My friend is going to tie the knot.我朋友要结婚了。
B: To tell you the truth, I'm very impressed that you remember. I thought for sure you would forget.
A: How could I forget such an important day? This is our wedding anniversary. Look at that case over there.
B: What's in it?
A: Please open it.
B: Oh, my god, a diamond ring. It looks very beautiful. You're so nice to me. I really like it very much. But it must be expensive.
A: Don't worry about the price. I just want you to be happy. You're more beautiful than this diamond ring.
B: I don't know what's going on, but I love you now more than the day we got married. Thank you very much.
A: You're welcome. Happy anniversary.
