I once knew a man who was in Mensa (’scuse me, Mensans) and who would not talke to anyone who wasn’t. How smart is that?
Not very smart! It can be very trying when talking to people with significantly lower intelligence, but this is where many of the problems are highlighted that smart people solve and for which they receive recognition. Smart people don’t generate many problems, or at least ones they will discuss. Many feel any problem they bring up must be significantly difficult to make them look even smarter. Many times these tend to be more argumentative than solvable.
Like any other ability or disability it is what you do with it that counts.
