This guy was a jerk and mistress Suzy did not want him to get used to being a jerk. Someone had to do something about it and she did after he was rude to the old couple in her building. She went to the guy's house and she strangled him so badly that he had no choice other than to go to the old couple and apologize for her to forgive him.
Lady Sue was hurt by the fact that her boyfriend took her for granted. She felt that she needed to make a statement and since he clearly did not know her well, she used her strength to pin him down and tie him before she choked him. He cried and begged her not to continue with her torture but she told him she was not going to stop. He promised to change immediately and she stopped.
Mistress Gaia did not want to be associated with bigoted people. And it was unfortunate that her next door neighbor was one. And he did not hide his bigotry. So she chose to teach him to shut up or accept that his views offended people and be ready for the consequences. When he chose to accept the consequences, she choked him as punishment and told him his that his views deeply offended her.
