I'm getting mixed messages on what is the "done" thing, so would appreciate a steer from the wise heads of Craicnet. I used to work with a really lovely woman who has now retired. I am extremely fond of her and love meeting up. Her daughter is getting married soon (I have met the daughter a few times and she is also a lovely woman but we are not pals, and I have never met her husband to be). She has invited myself and partner to the full wedding. Now, for various reasons we can't go. I was just going to send a card, but I have been told that the expectation would be to send a gift/money as well as the card. If so, what would be the norm?
