Well, you shouldn't say something like, "it's not my fault" because that sounds sort of... I don't know, whiny.

But, it's true. We don't have the same abilities as the magical people do, but we did our best in our own way. You can't tell someone their best isn't good enough, because that's wrong, too. It's perfectly okay to be annoyed with a friend, but we should probably say something to her.
