My brother, who doesn't know I'm trans, came into my room last night, and asked, completely out of the blue, "Hey......um...... You're a girl, aren't you...?". I've always been a bit nervous that he'll figure it out (not sure if I want him to or not), and I wasn't sure if he had and was asking about it, so I stuck with a neutral "Why...?". "Well", he said, "my girlfriend and her mum went bra shopping and [girlfriend's name] was told she was a 12 FF. What do I say to a girl to commiserate?".
Of all the possible answers I could have given, I'm so glad I didn't and just stuck with
"Why?"!
(And I redirected him to Mum for girly advice

).
Anyone else have a "glad I kept my mouth shut" coincidence?
