Celebrating a friend’s anniversary is its own kind of thing because the message you send is not from inside the relationship, it is from someone who has been close enough to watch it, to see the real version of it across ordinary time and specific moments, and that position comes with its own particular warmth and its own way of saying something that only a friend who has been paying attention could say.\
Sorted by tone so you can find the one that sounds most like you and most like what you have always wanted to say about the two of them.
