Earlier today, I e-mailed a friend of mine. In the e-mail, I called her "Miss K."
In her responding e-mail, she called me "Miss S."
It was just a little gesture, but it made my day!
I've known this friend, a genetic female, for nearly ten years. For most of that time, she knew me only in male mode.
I came out to her about a year ago and she has been very supportive.
We have plans to go out to dinner soon (both of us en femme). Dinner is on me.
