Oh trust me, we've done our casual shitlording to her and we don't think she's noticed. Good example was, one time my pants were getting a little tight and she was in the living room, so I said to my friend who was walking through "hey my pants are getting tight....you think i'm getting FAT!?" (changing with my door open, but you can't see my room from the living room at all because our halls are narrow and crooked) and I said it as if getting fat was the worst thing ever (which it is) We used to have our now ex-girlfriends over a lot, and she hated that and gave them mean looks. Our ex's were both proper shitladies Anyway, we don't care enough to call her out because it's easy to ignore it and move on with our lives. And honestly we enjoy making fun of her lol
