Trans-folk are the only people I try to avoid using they to describe. I know it can cause discomfort, and potentially lead to others getting confused about pronouns if anyone listening doesn’t know my grammatical quirks.
For everyone else I may use they for a variety of reasons. One of the most common: if a person’s gender hasn’t had clues about it in the conversation, I’m likely to just default to they. Like if I’m just calling my partner “my partner” rather than their name, I won’t then specify gender with pronouns. Disclosing gender when it doesn’t matter can feel weird.




Space heater in the US refers to something different.
Home heating may be done using steam in radiators. As far as I’m aware this is most common in older buildings or in the north. New York has district heating that seems to resemble district heating found in parts of Europe.
A space heater in the US is a resistive electrical heater, that isn’t usually connected to the main heating system for the home. Typically these are small portable units, and they’re used to heat just the room they’re put in. Your thermostat might control several rooms, but you might not intend to be in those, and night not want to pay to heat all of them. Or it’s unusually cold, so you use a space heater and just stay in that room.
