My "worldly" Catholic family came to my daughter's wedding at the KH and thought it was one of the nicest weddings they had ever been to.
Just a hunch: was this the first time they heard The JW Wedding Talk? They may have thought it was carefully planned out, personally prepared by the elder especially for the happy couple. They wouldn't know that every couple married in that hall gets the same one.
Hunch #2: They didn't think it was particularly wonderful, but were being nice and trying to not offend.
