being inconsiderate is it in your DNA?

I would think it is more of a learned behavior because if no one ever told you to say Thank you or please or that it is wrong to say or act in a manner that is inconsiderate then how would you know the difference. A person would think this is the way your susspose to act and behave and would have no regard for anyone else.

well i can only tell u my best guess or philosophy on this subject since im not a Dr or the like.. anyways yes it is posible for it to be in someones DNA, however i think the acting on it (or rather not acting on consideration) is a learned thing! lets take for example, the foods we like are encoded into our DNA right, well that doesnt mean we cant eat other foods.. ive never heard of a possibility of being allergic to consideration lol. i think it really boils down to ppl just not caring about others, or perhaps its a mental problem, like a boarder line patient. but mental issues aside, i think its deffinately a learned habbit!
