Singular "they" dates at least back as far as the 14th century, and I've yet to meet a person who objects to it but does not use it themselves now and again without even noticing if you observe them speak enough. It's entirely integral to English.
The interlude during which some pushed for "they" to be exclusively plural, was a mere brief blip in the history of the language.
It's also a couple of centuries older than singular "you", so if you want to complain about a pronoun changing between singular and plural, that's a better candidate.
I’ve been writing they to refer to individuals in the third person for five decades. Usage of they as a neutral singular pronoun began in the 14th century. Stercus alibi iace, outrage monkey.
It's so funny how outrage poisoned partisans have such crushing issues with pronouns. The word 'They' has been used to refer to individuals for hundreds of years. Get a life
I dont know, ask the commenter - he who reads OPs story and comments on it, projects himself into it when commenting on it.. there is no fixed answer to this.
