For people you’ve known a long time please have patience with them adjusting their habitual pronoun use. 

You likely struggled for many years with your identity, probably in secret, asking everybody around you to just instantly change their view of who you are overnight is a huge thing. It takes time to adjust. 

About 10 years ago a guy who was in my extended friend group came out as trans. A few people knew for years about the struggle, most of us did not. It was a huge surprise and most of us tried to adapt. After about a month, SHE snapped on a bunch of us who were trying to accommodate but would slip up with the pronouns and “cancelled” our friendship in one group text. It took her 10+ years to come to grips with it and she expected us to do it in 30 days. Fuck that.

Yup.  Someone I was dating started as she but switched to they/them as pronouns. I'm fully supportive of that but like, you present entirely female, wear a ton of makeup, dresses, lingerie, etc.  I'm not intentionally misgendering you when I use the wrong pronoun, but when talking/in conversation my brain doesn't always remember to switch the pronouns since it's a conscious thing I have to do.
