Dear Prudence,
Recently I received two separate announcements letting me know that I’m not invited to the wedding of a friend. Both of these came out of the blue; I had not precipitated them by asking if I was going to get an invitation. Apparently, it’s a trend for brides and grooms to tell people who didn’t make the cut that they aren’t going to witness the special day. (Google "How to tell someone you're not inviting them to your wedding.") I have no idea how to respond. It seems churlish to say that I’m relieved, but it’s also awkward to admit my feelings were hurt. Please help.

Re: I want to know who does this
Explain to them your budget for the wedding and let them know how important they are to you.
Example: I would really love for you to be in attendance on such a special day in my life, but because of out tight budget for the wedding, I was not able to invite as many people as I would have liked. But if possible, I would love for you to help me_______(find a dress, look for a shoes, pick a cake, etc...)
And this too:
Never flat out say, "You are not invited," but make it clear that there is a reason. If possible, invite them to be a part of the wedding by being a host or hosts. Also, invite them to your wedding shower, if possible.
No matter how nice you may tell someone that she's not invited, she may still be upset.

and really, what kind of response is the announcement asking for?
But I can see some moron jumping the gun and sending out an announcement prior to their wedding date. Which is tres awkward IMO.
