Good VS Well

One of my BIGGEST pet peeves in writing is when people mix up the usage of good and well. The stylebook says that "Good is an adjective that means something is as it should be or is better than average. When used as an adjective, well means suitable, proper, and healthy. WHen used as an adverb, well means in a satisfactory manner or skillfully."

Although most of us don't think of the proper part of the sentence when we decide which word choice to use, perhaps we should. When someone says "I don't feel good" do they not hear that it just sounds wrong? Where does the common every day language and improper grammar end and correct grammar begin? When does it stop being a negative thing to use correct grammar outside of English class?

Either way next time someone tells you to "do good" on a test or if you "did good" on your paper remind them ever so gently that "yes, you did WELL!"
