A younger professional friend of mine and his wife have posted their anniversary picture on facebook. (Guess I think it's YLF, LOL')
Anyway, practically everyone is saying Happy Anniversary. I want to say that or something to that effect, But I also want to compliment her on her beautiful nails. Is that appropriate? And if it is appropriate, do I use her first name, as I do his, or should I say Mrs their last name.? I have not met her.
