Is 'no rest for the wicked' socially appropriate?

Posted by Ben on June 14, 2005

If you're in contact with someone who tells you they have been working really hard, and are determined to get as much work done as possible, is it socially appropiate to respond with 'no rest for the wicked'? I take this phrase to mean 'no rest for overly determined and enthusiatic souls'? Am I correct to use the phrase in this social context?
