I see Monica is still makes these subtle boasting and performative comments that frame her as the one you don't mess with—while subtly casting Brandy as the delicate one. It like passive-aggressive positioning and she keeps re-assigning their roles in the dynamic to make herself feel more comfortable about being the "hood" one of the two.
This is the loop that has them falling out over and over again.
When someone doesn't fully respect the essence of who you are, even when they try to understand, it's not worth it. Do the tour and keep it moving from that lady.
