morphenine,
You would enjoy
www.grammarlady.com's bulletin board.
You should especially read the Question & Answer section.
You'd really enjoy the Pet Peeves and Typos of the Weak(tm) sections.
And Language Funnies are great!
Roberta, While it is wrong to correct one's supervisor (even if the guy's an idiot), I would be more concerned about making sure anything going in my file (e.g. a writeup) was correct and clearly written, so there were no future misreadings.
So, asking for clarity on a writeup I think would be justfied (still won't make an idiot manger happy, though).
