Why do so many people get this wrong? “How are you? / I'm well.”
How would you answer the question "How are you?"
I'm well.
or
I'm good.
I notice that in American English, the latter is normally used, but I feel that the former is grammatically correct.
Same goes for questions like "How did it go?" Can one answer "It went well," or "It went good."
Which is correct?
