Getting an Announcement
Well, you're not invited -- but the bride and groom want you to know about it. Don't get mortally offended off the bat -- if these are close friends, they may have chosen to have an intimate family wedding and so couldn't invite all their friends. If it's not such a close friend, or it's a business associate, don't feel obligated to send a gift. It's a nice gesture to send a personal note of congratulations, but even that is not automatically expected.
