Along those lines, consider a brief take from Connubial Bliss. You are sitting on the bed next to your partner who's studying the latest Samsung TV-screen commercial on his laptop, about the SAMSUNG 40ES6100 TV LED 3D. And it's great, this screen, its display, the brilliance, sharpness, vibrancy, so many parameters, the best image ever. You can see it, can't you? We must buy the new Samsung screen now, it's better than anything before. "Better than your laptop?" the jaded you in you is about to ask, and because this is us, we actually do (ask): "Better than your laptop?" "Of course," is the answer (of course). And because we carry traces of school-mastery pedantry in our DNA (where else, not our fault), we continue the conversation with "How is it possible that your laptop screen is able to shows an image quality exceeding its own image quality," to which your partner (still sitting on the bed next to you) will reply "Shut up!" or "You always do this to me," or "This is also a Samsung".
Luckily, the analogy breaks down very quickly since there are other dimension absent from this picture, such as time, complementation, or wit. In case: we can show other people's smartness by giving them a quick mind (we have minutes, if needed hours, to write a quick comeback for Alex), or equip them with knowledge we don't possess by finding it on the internet, and so on.
