Yeah, it did look like some personal signal, like linking herself to the otherwise objective content of the sentence, but there also was that lame turn of phrase that she turned into something more entertaining. A complicated message, then. Which is fun.
That's what I mean about an Se bridge that prompts Ni. Exactly what the signal stands for is unknown, and, in theory, will prompt speculation, and possibly greater interaction. It's a test of sorts too, I guess. You're supposed to know there's meaning to the gesture but that it's idiosyncratic.
Furthermore, it can be written off as something just for fun.
