Whenever one of my students often say "I'm okay" to respond to my "How are you?"
I was thinking to myself 'Do i need to correct him or not?"
Is it usual to say "I'm okay" to "How are you?"
I don't see it as "surly" either, though tone of voice would matter more than words.
I don't understand Bill's explanation.
I'm okay can mean "not great" or "just fine" but the first meaning doesn't come from stressing the first word. I'd say instead that it's a rising inflection on K that says all is well and a falling K suggests not great.
I'm not a teacher, but I write for a living. Please don't ask me about 2nd conditionals, but I'm a safe bet for what reads well in (American) English.

It's "Yeah, I'm all right."
He's saying it with a falling intonation/inflection, isn't he?
