My cousin's aunt's sister in law Nessie was betrayed by her own brother, Lando, who told their mother that she spent the holidays in the Bahamas with her in laws, instead of in the hospital. The mother in question was a piece of work, Nessie should have told her to her face, and taken the heat. BUT Lando shouldn't have spilled the beans, that breaks the rule of rules. What if Nessie just ignored her brother's backstabbing?
This takes fortitude and attitude. If you ignore in the right way, you aggravate everyone, because it's just like saying, whatever. Who cares about you? If you do it the wrong way, you just look like a mealy mouthed doormat, inviting people to wipe their feet. So it's dangerous. If you are ignoring cause you are afraid of a fuss, believe me,
nothing fuss likes better than fear.
