A turn of phrase

I have been giving this blog short shrift this week while I prepare for a new semester, but I did find this great site that offers explanations and origins for a bunch of phrases and idioms. In business writing, it's generally a good idea not to use idioms, because they can confuse others, particularly if you are attempting to communicate with people of another culture. You really need to knuckle down, or work hard, to remove any trace of cultural bias in your communications.
