Just curious. This is more of a play on words thing so no need to suggest alternatives if it's a no. Thanks!
In deep or close 3rd POV, yes. In omni, yes. But in both cases, you need to show the reader why the POV character thinks this person is tedious.
It's more of an initials thing. TDS. Get it? Play on words. It's more for me than anyone else but I figured a reader would get a kick out of it if they figured it out.
