Great question.
At work people are doing a much better job now, 3 months later. A few people were returning employees who weren't with us when 'the memo' went out... it was funny, going up to them a month and a half after I came out at work, having no longer been hiding my boobs, and wearing my name clearly displayed on badge.
Me: Soandso
*holds up name badge, bounces in place, making boobs go up and down*
Me: I think you missed the memo. This name now.
I've been giving people a lot of rope regarding using the wrong name and pronoun. Most of these people have known me at least a year, if not 3. When someone uses the wrong name twice in a row, I discreetly remind them. If I do it on one mis-used name, EVERYONE launches into this big apology speech about how I'll have to give them time to adjust...which is what I told everyone when I transitioned in the first place. So it's not worth doing it on one slipup... yet.
Now when someone uses the wrong term/name like 5+ times in a conversation, I'll call them out on it pretty blatantly.
A lot of people catch themselves now, if they accidentally screw up. The smart don't get hung up on it and just let it roll, which is how I prefer it honestly. I don't WANT the big deal apology, I just want them to pretend it was like calling a Jason, "Mike" on accident.
Dad's called me by my girl name on and off... he used 'dear' to refer to me a few times last week. I figure once I get things completely sorted legally I'll crack down on my parents. Still no 'she' from him, and only rarely from mom. Of course, mom has a bias against me, believing that i'm not actually trans...
