Susan was full of resentment.
"I know you heard me tell you to leave me the hell alone" she repeated at Richard. The fact that he had just concluded that what Joey claimed about her was true. It pissed her off like nothing else in the world. She used to think that since she became a mother, it was easier for her to curtail her temper, but this scenario she was having with Joey and Richard was proving her assumption wrong by far. She was losing her mind.
"If you touch her again, I'm going to have your hands cut off, since you can only afford to be a mad bully with them" Richard warned Susan. An enraged Susan bit Richard'ons hand, the hand which he held on to her wrist with and refused to let go, she bit him so hard, bite marks sprung upon the area that her teeth had dug into.
"Mad fucking dog" Richard barked at Susan, letting go of her hand and sneering at her.
