The person in front who has dared to come up against your "opinion" is NOT an empty TIN CAN and nor is he representing any company who sells any of those EMPTY TIN CANS. Why am i suggesting you take such a drastic view ? because like you even a TIN CAN needs R:E:S:P:E:C:T. and i would like you to give him some by NOT considering him a .. a TIN CAN. well ofcourse he can be the tin can you have always liked to play mental games with ... but .. but .. if you hold this stand of giving some respect to the individual you will see "where is he coming from" . He may be wrong but you need to know what premise did he based his "wrong" conclusion upon. Because if you probe with a few encouraging questions you will eventually know the premise of his "logical deduction" , how will that help ? One it helps by reducing the tension in the air, Two you give him respect by taking active interest in his "thought process", three if you now still feel that the premise on which he has based his conclusion is at fault, i would recommend you to attack the premise, and by attack i mean ask him to strengthen his foundation in accordance to you "still probing questions " For example if you dont like ascending ordered list of things, dont push your new list in his face instead go like "what do you think one stands to gain by having a ascending ordered list ?".
Most people if you feel were on a "wrong side" of an argument give away at this test, and now convincing them about your version of the argument is more automatic in nature, and no blood is spilled, the swords are not drawn. :)
