So instead of shitting up the thread I'll actually contribute my story.
I had this friend, lets call her Suzie. Suzie was a bit of an aspie and "one of the guys" type of girls; not really a tomboy, but felt comfortable around guys and shared a lot of stereotypically male interests. Well Suzie would sometimes have what she called "boy days;" days where she'd dress as masculine as possible. We'd always treat Suzie a little softer on her boy days, because she always seemed extra touchy about things. A little more sensitive to banter, a little more quick to storm off in a huff.
So one day I'm out chilling with Suzie, having a smoke, just me and her. We're talking bad relationships, and Suzie trumps mine because she got groomed by a creep when she was 14. I'd known this already, but then she drops that she still has pretty severe nightmares about it. And I ask, in the gentlest way possible, "Are those the days you dress like a boy?"
Suzie: "Yes."
I'm quiet for a long bit, and don't let anything show. Then, as casually as I can I say "Sounds like it's a coping mechanism."
It's Suzies turn to be quiet. Then she says "I never thought of it like that."
She never had a boy day after that. Maybe she had a breakthrough, maybe it was the new anti-depressents they got her on not long after our talk. I don't know, I'm no psychiatrist.
