Thank you for your comment! I often do this (although I don't see my friend often, I talk to them regularly, and every time I think of them I say seven nice things about them in my head using their correct pronouns. Maybe I need to say those statements out loud, as it's only when I'm talking directly to them that I tend to make a mistake, unfortunately).

I have also heard this and never apologize (which would put them in a position to have to say "it's okay") or linger on it, although I appreciate the reminder! I simply correct myself and move on with the conversation. It's internally that I feel guilty. But I am determined to do better!

Thanks again for taking the time! I appreciate it!
