I down voted because of the "surely youre joking" comment. Its a petty passive aggressive insult to the parent, like the parent post was so obtuse that they must be joking. Ironic to me in an etiquette post.
Oh, but it was just an allusion to him, the venerated (and venereal) God of violating etiquette, Richard Feynman.
Thanks! I noticed it only started after I added the last paragraph, which contains the word a man shall not use on HN, not even in discussing gender etiquette of Victorian Fucking England.
No, that part was fine. Your 'surely you're joking' is extremely passive aggressive and severely weakens your entire comment.
