Yeah they don't realize how damaging that is and if you've ever tried to change how you refer to someone, you know how difficult it is. It took my youngest daughter 2 months to get the name straight and she lives with us. It took another month to get her pronouns switched over. It took another month or so before she stopped treating me like a guy. The older ones won't even refer to me by name or pronouns, but at least they don't duck out of family activities when they have to be seen in public with me, so I'll take it.
The youngest also wants us to de-babify her name. I don't even have to remember pronoun changes and I'm having a heck of a time remembering to do that. She's not as adamant about it as I was though, so I only get a reminder once a week or so. I'm trying, but it's difficult.
Friends have been the most difficult for me. They really don't seem to get how scary it is out there to be pegged as trans. I went out to dinner with my best friend and the waiter was clearly not sure of my gender while presenting female (because I was full time). My best friend for over 35 years noticed that I didn't have the drink I ordered yet, so he called the waiter over to let them know starting with a quiet "he" didn't get his drink. Confused look by the waiter. HE didn't get his drink. Confused look still. HE while pointing at me didn't get his drink. I was like I guess I can take this attention, but peeing is out of the question now.
I had another friend in a restaurant repeatedly call me dude and with his loud commanding voice, kept reminding me how hard it was for him to start referring to me as she after all these years. Both of these happened in a steak house within a week of each other. I need to stay away from steak!
Yet another friend, just a couple weeks ago, finally talked me into meeting up at a bar during happy hour. I was already pretty nervous when she decides to refer to me as my old name to the waitress, then apologizes telling me how hard it is for her to see me as a girl now. The number of looks I got after that was astounding. I'm whispering to her to quiet down and she's saying she'll take anybody on that tries anything. A room full of drunk guys in the middle of the country does not sound like a situation that she could take on herself.
Nothing ever came of any of them, as scared as I was, but I felt like I couldn't actually use a bathroom after each of them. The bar was 1.5 hours from my destination and I needed to pee, but she identified me as trans to half the bar. That was a fun ride home!
