If you do this in a small-talking country, people will think there is something wrong with you and avoid you like the plague.
The proper answer when asked "How are you?" is some variant of "Good." Occasionally, between acquaintances, an "Oh, okay I guess" is acceptable on Monday.
If you see the person every day, the rare "Been better" is begrudgingly accepted, but only if you obviously have a cold or some other illness. If there is any doubt in the recipient's mind what your inconvenience may be, or worse, if it's obvious but may cause them to feel anything other than a fleeting trace of empathy, expressing it is forbidden.
Would you happen to be English by any chance? Your English is flawless and you describe a mentality I've heard is typically English. You're expected to keep those little polite words coming and never burden others with your problems, weaknesses or annoyances unless they are your close friends - or unless you're talking about something generic like the weather.
That would be telling. :)
Thank you for your kind words. I take great pride in my literacy and writing ability. You may have just inspired me to write again sometime soon. :)
