If a person doesn’t want to take responsibility for the consequences of their actions, they may try to blame others. Don’t accept blame or try to fix things for them when you’ve done nothing wrong. They need to learn that if they want different outcomes, they will have to make different choices.
OK, you screwed up. Something’s gone horribly, horribly wrong, and it’s all your fault. And now, it’s time to pay the piper.
Maybe you lost your company’s big client. Maybe you forgot to do a critical part of that big project. Maybe you weren’t there for someone when they needed you, even when you said you would be. Whatever the situation, someone trusted you to do a job and you failed.
