One of the important factors of your wedding is the priest/pastor/minister/justice of the peace, who will be officiating at the wedding. The more you know them, and the more they know you, the more enjoyable the ceremony may be as they will be able to personalize it and add some personal comments or stories.
Having a ceremony that is personalized does not mean that it has to be exceptionally long and boring for all the guests, but a story or two can be shared to make the ceremony more personal. Just a few personal touches can make a difference in the personality of the ceremony. A funny story or a serious story both work but it is important that the story feels natural and not forced or made up. Sometimes the story only relates for the time that the couple has known the person conducting the ceremony as they have not had a relationship before that. That may make it a little bit trickier but likely one or two stories can be found in that time. If not, a general but interesting story can be used.
If you have known the person marrying you for a while, especially as a couple, it can be much easier to find these little antidotes to add to the ceremony. You only need a story that takes 30 seconds and it does not have to be long and involved just a little something to add interest to the ceremony and wake up the audience.
