Thanks for the share tokens. The long article from the summer includes various expected comments:
From her first days at Abbotsford Primary School in Glasgow, she knew she was different. Everything about the girls’ world appealed to her. Not much about the boys’ did. When the girls went to their part of the school yard, she wanted to follow but already sensed that sissies weren’t tolerated.
She coped by creating a secret world, tiptoeing into his sister Elizabeth’s room at their 11th-floor flat in Pollokshaws, south of Glasgow. Elizabeth was a year older and her clothes fitted Robert. Picking the moment carefully, he would sneak into his sister’s room and put on her clothes. Dressed in his sister’s clothes, he felt more comfortable and more secure. He liked that feeling.
Every. Single. Time. Boy doesn't like what boys are expected to be like, so decides this means he isn't a boy. If he's not a boy he must be a girl. He does after all like girly things. They give him a special feeling, especially after puberty. How handy for a boy to have a sister of a similar size! But it has to be a secret. How can a boy admit to liking those things? He can't! Poor, poor boy. Sorry! Slap on the hand. Poor, poor girl. Never mind, though, once the girl has spent years in a male-dominated career, got married and fathered 
children, those obliging medics will step in and help the now middle-aged girl to be her true self at last. Shame about the wife, ex-wife and children, but they'll cope.
Not a scintilla of sympathy for those whose lives have been turned upside down by the transition, nor for his sister's feeling on discovering that her brother has been rooting through her underwear drawer and using her makeup.
So frustrating. I am a couple of years younger than Robert Millar and I also lived in Scotland when young. I can well believe that life was tough for gender nonconforming boys, but some managed it.
