Wedding rehearsals are more than just run-throughs of the ceremony. Often a rehearsal is the first occasion families of the couple meet. Of course, even if they have met, relationships and interactions between families are usually still awkward and stiff. This is why at the beginning of rehearsals, with everyone seated, I ask the couple to introduce their family and friends present. Beside names, I request they include some interesting detail about the person introduced. And I insist people stand as they named so everyone is sure to see them. It helps break the ice and creates opportunity for new relationships. I also encourage couples to do assigned seating at the rehearsal dinner, even if very informal. Again, it's chance to help create new relationships.
