Why Are Bridezillas Tolerated?

Alas, to err is human, to forgive divine. To put it bluntly, it's cuz we as human beings care about other human beings. The more you care, the more s**t you put up with. Everyone has that one thing that could cause them to godzilla-out. Weddings, promotions, theatre, births, etc. For whatever reason it is do or die for them. Everything must be as perfect as possible or the world will end as they know it. Fortunately, or unfortunately, it's only the top tier people in their lives that are put up with it. People who are family and close friends who will go "what the hell is wrong with you?" and they keep loving them anyway. Most people in top tier positions realize these "zillas" will un-hulk when it's over and thing will return to normal-ish.
