That's right, but the insidiousness of real problems has always been part 
of the game that we are playing here.  One needs the seventh sense to look 
behind the facade of everyday incidents.

In recent years I find myself more and more distracted by increasing noise 
on the net, and I don't even have a smartphone and I am not a member of 
Facebook and the like.
