My objection to the use of the plural pronoun is documented elsewhere. This annoying (to me) linguist twist finds its way into Burt’s vocabulary by way of reduplicative paranesia.
“When are they coming?,” Burt asks. “He works alone,” I say about his PT, “and he’ll be here at 4 pm.”
He had two weekend aides, but I fired the “bad one” which made him happy. The one remaining gets to hear how bad the other guy [him himself] was.
I understand because I found out just how awful his wife (poor moi) was. He has a new wife (moi again, just in luckier circumstances) now.
