There are always going to be some bat shit crazy peeps butting in to the planning. At least your nutjobs are willing to pay for their insanity.
I threatened my father, aunt, and 3 uncles the weekend before my wedding that if o w cross word was uttered about my grandmother's estate, I would throw the lot of them out on their collective asses, wedding dress be damned. One uncle looked at pop and said something on the lines of "she would, wouldn't she?" Pops reply was " I ain't gonna do anything to find out!"
