You can't just say "let's pretend it never happened", because it did happen. You complain that people cannot suspend their disbelief, but you live in a world of suspended disbelief. You can't just push everything to the side and keep going all the time, because there comes a point at which you have to acknowledge what's happened and learn from it."
I wish that this wouldn't keep playing back in my mind... but some people are just... complete repeats of others.
