Ooops

How do you know that you don't know something if you don't know it?

This was the question TBG posed after recognizing that 75% of the kerfuffle over the doctor's return call was not because the doctor didn't make it but because modern technology was, in this instance, totally inaccessible to him.

He was unaware of the feature that would have avoided a lot of angst.  

And so he asked how we could hold him responsible for not knowing something he didn't know.  If he didn't know it how would he know to ask for it?  

All of these are reasonable interpretations of an uncomfortable situation.  But TBG is right - he was an idiot.
