This is why I have a stubborn insistence that people explicitly admit fault before I accept anything resembling an apology. It's not my desire to dominate or humiliate a "defeated" foe, but to know that the person actually understand what the mistake was and has internalized it and isn't simply trying to handwave their way back to status quo. Otherwise, I absolutely cannot trust they are unlikely to do it again.

I expect to be very disappointed over the next few years. :)
