A father and son were talking one day and the son says to the father "Dad, is it true that in some cultures, the groom doesn't know the wife until after they're married?"
The father replies "That's true in all cultures, son..."
An old friend told me that his dad had said to him on his wedding day:
"You can be ~right~, or you can be married, but you can't be both."
I think that applies to both sides.
