A tip to help with memory; every time you think of that person, use the correct pronoun in your head, like “I wonder how Lou takes his tea.” It is super helpful when relearning someone’s name/pronouns after they come out. It also helps with neo pronouns. I have a friend on FB who uses neopronouns. Every time I see a post from faer, I thinks of faer’s pronouns, because fae/faer is a difficult set for me to remember. In fact I typed “their” at one point and had to fix it.
