Does anyone ever actually feel "fine"? I never say that I feel fine unless someone's asked how I am.
"Fine, thanks." No, you're right, I don't generally feel fine. That's like commenting on a "fine" day. It all depends on what one means by the word. Rather non-specific. How are you today? Hm, not really sure how I feel but thanks for asking. No. Best just to say "fine" and continue on.
