Your nerd has built an annoyingly efficient relevancy engine in his head. Its the end of the day and you and your nerd are hanging out on the couch. The TV is off. There isnt a computer anywhere nearby and youre giving your nerd the daily debrief. Spent an hour at the post office trying to ship that package to your mom, and then I went down to that bistro you know the one next the flower shop, and its closed. Can you believe that?
And your nerd says, Cool.
Cool? Whats cool? The business closing? The package? How is any of it cool? None of its cool. Actually, all of it might be cool, but your nerd doesnt believe any of what youre saying is relevant. This is what he heard, Spent an hour at the post office blah blah blah
You can be rightfully pissed off by this behavior its simply rude but seriously, Im trying to help here. Your nerds insatiable quest for information and The High has tweaked his brain in an interesting way. For any given piece of incoming information, your nerd is making a lightning fast assessment: relevant or not relevant? Relevance means that the incoming information fits into the system of things your nerd currently cares about. Expect active involvement from your nerd when you trip the relevance flag. If you trip the irrelevance flag, look for verbal punctuation announcing his judgment of irrelevance. Its the word your nerd says when hes not listening and its always the same. My word is Cool, and when you hear Cool, Im not listening.
Information that your nerd is exposed to when the irrelevance flag is waving is forgotten almost immediately. I mean it. Next time you hear Cool, I want you to ask, Whatd I just say? That awkward grin on your nerds face is the first step in getting him to acknowledge that hes the problem in this particular conversation.
Which makes me almost like "the stig".... 
. I never zone out.
