You know the one... A key that opens many locks is a master key, a lock opened by many keys is a shit lock... It struck me while poigniant as deeply flawed, so I thought I'd ask more about it. master keys are special for a reason--there are less of them. So there's thousands and thousands of plain keys that are designed to fit one lock,but can't open a single one that somehow believe they are going to become a master key, which is unfair to them. Surely they would be happier understanding that it's okay to get what they deserve?
