If she did not listen to the word herself, she will not believe that Rosaline had just told her to back down and even should be afraid of a maid that has disrespected her. Even though she was Mary's caretaker, she was still a maid. She should not have power that is similar to the owner of the house.
Feeling the eyes was still following her, Rosalin sighed and started to explain with a worried face, "she always took advantage of Miss Mary's feelings of pity and always asked the girl to help her. She almost got fired several times, but after seeing Mary constantly crying, master and madam couldn't bear it and always forgave Mary's mistake."
The thought of one maid being overpowered and oppressing another maid with her power bothered her a little. She wouldn't really care if that maid didn't get into trouble with her, but this maid actually looked down on her and dared to talk to her like that, let alone prank her. This was just too much.
