I suspect the I.Q., SAT, and school grades are tests designed by nerds so they can get high scores in order to call each other intelligent.. Smart and wise people who score low on IQ tests, or patently intellectually defective ones, like the former U.S. President George W. Bush, who score high on them (130), are testing the test and not the reverse.
Chester nods all the way through this, but does not rudely interrupt Randy as a younger nerd would. Your younger nerd takes offense quickly when someone near him begins to utter declarative sentences, because he reads into it an ssertion that he, the nerd, does not already know the information being imparted. But your older nerd has more self-confidence, and besides, understands that frequently people need to think out loud. And highly advanced nerds will furthermore understand that uttering declarative sentences whose contents are already known to all present is part of the social process of making conversation and therefore should not be construed as aggression under any circumstances.
