This old man thought that his age exempted him from being nice but that was not the case. He was rude and nasty to mistress Abigail and she had to do something about it. This is because she did not want him to be nasty to all the people he met as he did not know them, they did not deserve it and he did not know what some of them were going through. So she turned him into a pee slave and made him drink pee as punishment.
