The person giving the wedding talk is supposed to quiz the bride and groom whether or not their courtship was *chaste*.
If the KH is used ALL in the wedding party must be in *good standing* including private reproof.
Don't know about confetti but I attended a JW wedding where the guests were given little vials of bubbles. The kind with the wand you blow through. It was a first for me. (It was held outdoors).
