Out of curiosity, what age range are these folks?
I'm having to deal with some people in the "coming of age" range and it is rough. One of them says their preferred pronouns shift constantly, but people should be able to tell based on how they are acting in the moment whether they feel feminine or masculine, to use 'they' is a cop out signifiying that someone doesn't care enough to tell.. The person decided mid conversation they felt more feminine and was disappointed I didn't swap without being told...
I try to be understanding, but folks need to recognize that even if their own internal life and identity is a rich and complicated thing, they need to simplify it for those of us on the outside and understand we can't possibly see inside their mind to understand all these factors that they think should be obvious.
