I just found a beautiful thing online:
The Fine Art of Being Come Out To: A Straight Person's Guide to Gay Etiquette.
Quotation:
Once you've spotted a casual coming-out in action, your next move is to avoid dropping your water glass and segue into a suave, low-key response that will convey to your outcomer that his/her communication has been noted and logged. A common mistake at this juncture is the overdone expression of support. A response along the lines of "So you're gay then? Well faaaaaaan-TAS-tic! I'm just tickled pink, I think gay people are lovely" will certainly get the message across, but will also convey the unfortunate impression that you expect to be awarded a medal for demonstrating common human decency. More appropriate responses include "So how long have you been together?" or "Uh huh. Can you pass me the salt?"
The same author writes Holmes/Watson in which Watson is not a hearthrug.
