I had this work friend at my previous job who was gay. Lovely kid, from a kind of traditional family.
He hadn't told anyone he was gay, because he was scared of being judged. But... thanks to the resident lesbian, he was outed to everyone without his knowledge because she clocked him and asked everyone about it while he was off work.
Everyone then put the clues they'd noticed on their own together rather than what they were doing beforehand, that being remaining blissfully and politely unaware of how his variety of behaviours linked back to him being gay.
Had I already clocked him? Absolutely. But I should not have been told about him, before he chose to come out to me.
This pride month, remember that even in the most accepting of environments, even if you personally feel comfortable being out where you are, that doesnt mean someone else around you is too. Do not assume that someone is comfortable with everyone knowing, or that everyone knows.
Because we might not have known. That person might not have told us yet. We might have been politely ignoring the signs because we didn't want to assume.
It's not your place to tell everyone someone else's business.
