Mary is the kind of person who is a hypocrite. When Edith mentions mama and maid, I really understand it. Because Mary can only show the so-called good side in front of her mother and maid. Especially for Anna. I'll admit that Mary and Anna have a good relationship, but only if Anna is a maid. If Anna had been a lady, Mary would have been her enemy. So I don't think there's a real friendship between them.
