Dear Annie: A co-worker of mine sent a wedding "Save the Date" card addressed only to me. I've been married for eight years. When the invitation came, my name was the only one on the envelope, and the response card was already filled out, marked for one person attending. Obviously, my husband is not invited. After speaking to a few other co-workers, I realized I was not the only one. All of the other invitations were the same: no spouses.
