Years ago, I sent an angry (well, frustrated is more like it) e-mail to my director in which I extended a "cordial invitation (to a group of senior bureaucrats) to have carnal relations with themselves" (sic!) if they couldn't accept a certain point of view. She apparently didn't read or digest the note thoroughly because she passed it on to her director. Nobody got in trouble for it, but I get a delicious private tickle whenever I think of it.
Get to know your euphemisms, kids! They are the trojan horses that get you in the gate of the castle. 🙂
Just be nice to each other.
