<<Common sense applies more than it suggests, courtesy, values,manners & respect for others. All of which are excellent virtues to have>>
Really? Values are a more fundamental characteristic to personality than any of those others. For one thing; everyone has them - good, bad or indifferent.
Manners and courtesy are social rituals which depend on cultural environment.
Respect for others is a good thing I agree but i'm not sure what 'common sense' has to do with it.
I think your definition of common sense may be a little idiosyncratic. Here's one from a dictionary -
common sense
–noun
sound practical judgment that is independent of specialized knowledge, training, or the like; normal native intelligence.
