We used to have a cleaning lady, super nice woman, who my mom would just straight up humiliate.
This lady was really fat and had a binge eating disorder and my mom would take pleasure in buying sweets (which she doesn’t like) and leaving them around the kitchen in hopes the lady would eat them, which she always did.
Then, my mom would confront her about that, her weight, her eating habits and the like.
Seriously, this lady was an amazing person and my mom, for some bizarre reason, fixated on making her miserable.
I got into a bunch of fights with her over this very issue, but she just wouldn’t stop, so eventually the lady quit; We’re still in contact and she’s doing much better, which doesn’t surprise me because my mom was a raging bitch to her.
New cleaning lady is completely unwilling to take any shit, so my mom has had to deal with that, but seriously, when she confessed how she loved to tease her and manipulated situations to make sure she could… god, forget losing all respect, I was actually disgusted.
