There’s another example of a girl on my robotics team who got really mad at me. Now she didn’t tell anybody, nobody told me, and she didn’t dress differently or anything (again doesn’t have to but it helps) just became hostile when people used wrong pronouns. I haven’t made the mistake since.
Basically my cousin came out as trans and nobody told me so I deadnamed them. They got really made but weren’t dressing according to their new gender (they don’t have to) so idk how I was supposed to pick up on it. Later they detransitioned after becoming pregnant (hormones from pregnancy erased gender dysphoria, it isn’t common but it happens)
