I have friends whose son is getting married soon. I’ve known the groom since he was about 7 years old and I met his wife-to-be when they began dating several years ago. I am not invited to the wedding and that is okay. I would like to send a gift anyway. I’m afraid, though, that if I ask where the couple is registered - or ask about any wedding details - it will look like I’m trying to weasel my way into being invited. How can I get information about the wedding registry and send a gift without giving the impression that I expect an invitation?
