hi Portie,
word salad, of course, and you will spend hours (hopefully not days) trying to decipher it because...(spoiler alert) it is designed to not make sense
The game is 'one up-man-ship' and how cute, she called you a "teacher" (a back handed compliment for sure)
I've spent nearly my entire adult life trying to decipher border-splaining. You can't. Only they know what they meant, and how it was designed to hurt you.
My advice, find a good friend, a good book, a pet to pet, or any other soothing activity that will erase the entire episode from your brain, and if that is not possible, then just imagine retorting with "that made no sense" (but don't actually do it, just imagine you do) and move on.
It's the best revenge.
