or “Not too well, but thank you for asking. And yourself?”

Never go in to detail about your ailments. People really don’t MEAN it when they ask how you’re doing. It’s just the polite thing to say!

it also depends on what the person is referring to..if he’s referring to a certain point that you seem to know, then answer what you have to answer!!

If it’s in the US, than the answer “fine” is more than sufficient.

If you are in Europe, you can answer with what you want to say.

The second part of the question:

If the person asks you the question and looks into your eyes and wait’s for an answer… than it’s like “Europe”, reply honestly what you want to tell him.

If the person asks you the question and walks further…. than you know…. “Fine, thanks”

the proper response would be

Very well, Thank you

even if you’re not

or

Very well, and you?

err?
