Person 1: Where is emy?
Person 2: Oh she, is over there. Points
Person 3: hey person 1, emy doesn't refer to herself as she..
Person 2: oh I'm sorry. I had no idea about Emy and their pronouns...Hey person 1, Emy is right over there.
I find it easier if you refer to people by their names (preferred or otherwise) and just default to gender neutral terms like "they/them". Because it not a hard thing to do.
