Since June is ``bustin' out all over'' with brides and weddings, it's a good idea to catch up on all the details involved in making sure the Big Day will be one to remember. It will be, but not for the reasons you thought. Pond tells the truth about what wedding days are really all about. Essentially, she lets the prospective bride know that she will have absolutely no control over the course of events for the special day. Since the beginning of bridedom, certain forces have been in place that cannot be disrupted. Pond offers a quick course in how to get through the Rules of Engagement, who sits where at the reception, and how to cope with the tragedy of Postnuptial Letdown. A welcome addition to all those bride's books that tell how to do it the right way!-- Belinda Pugh, Kings Bay Subma rine Base Lib., Ga.
