One of the most significant faux pas I have made as an English teacher occurred during my year of student teaching. My mentor teacher, thankfully, was not above correcting how I spoke, and I honestly took no offense as I had never been taught the difference between “good” and “well”.
Needless to say, it’s a very simple lesson to learn, and while using “good” incorrectly as an adverb to respond the question in the example above in daily casual vernacular is fine (for goodness sakes, television scripts regularly have their actors say it incorrectly intentionally to mimic the public), the key is to know when to reveal your understanding of the difference and when to just let go.
A job interview or a formal setting in which an impression of knowledge and competence for the English language is expected: Use it. While spending time with family, friends, and acquaintances in a casual environment: Let your hair down.
