The biggest difficulty I've had recently was getting used to a "they/them" pronoun for a character who was nonbinary. Just like in real life, I've gotten used to seeing gender as a singular trait. Working with it in roleplaying helps me practice when I don't want to mess up in reality.I’ve had it at my table, the only issue has been with pronouns. When your looking at a guy its hard to remember to say “her” in reference to the character...but that’s about it
