Not “my” coming out, but…
I used to work in a factory in which there were, among others, a father and son. They were in different shifts. One day in the cantina, the father was saying that he was worried about his son, “he never talks about any gals, y’know, never brought a girl home… and he’s so quiet… I worry what will be of him when we’re dead, y’know”
One of the guys, who is about as subtle as a sledgehammer but also has the unfortunate tendency to be right, said “dude, I got news: your son is never going to introduce you to no gal.”
“Uh?”
“He’s gay, man.” Here the rest of us chimed in with appropiate synonims, in case Dad didn’t get it.
Dad: “He’s gay? He likes guys?”
Us: “Yeah man. Gayer than Liberace in a sequined Speedo.”
Dad: “But how do you know?”
Us: we’d all seen him at different times with a guy the same age who was very evidently his boyfriend
Dad: “Oh. Oh, OK! That’s good, then! I was worried he’d be all alone, you see”
Some other guy: “You mean you don’t mind?”
Dad: “Hell no, I did my military service in the Legion…” (the most macho outfit in the Spanish army) “Mind you, if his Mom ever finds out she’ll have a heart attack.”
I don’t know if Dad ever told Sonny that he knew, but it was kind of funny how scared some of the guys had looked during that conversation.
