Lady Mira noticed that this guy was addicted to nonsense and she could not tolerate such nonsense. She felt that the best way to deal with the guy was to shock him and humiliate him like never before. The mistress did it until she was tired before she felt that it was enough to let him go and she asked him to go but not repeat his mistake. He got the message.
This mistress chose to cruelly torture her slave by trampling him. She did not want him to disrespect her the way he had earlier that day. She promised him that that was going to be the last day ever disrespected her. She trampled him as cruelly as she was able to and she laughed at the poor loser as he tried to beg for mercy which she did not show him.
