If you are older, you can always play this one and sweep the board. Your wisdom has been ignored, your opinions have been spurned with contempt, and you accept this without demur. You know that you have no value in the world. That immediately puts your opposition in the terrible position of having to bring you back into the argument, of having to beg for any further advice; and as soon as an apology is issued, you can put it down for future use. You were slighted. If you were not, why apologize?
