Look, I fully support you transitioning. But if I was your co-worker I would be mad at you. You made me do extra training! Yeah I'll call you she and her and all that but.. Fuck you for giving me extra training.
(don't take seriously, I'm only joking but doing the corporate hr type training is a pain in my ass but I do support you and trans rights in general. In fact it's fucked up that people need training that basically comes down to "respect me and don't be an asshole")
