Food for thought but no teeth to chew

Hitherto, did you ever happen to come across people who seem to cast a first impression of great thinkers!!?? Later,disappointment is all you get.

Pseudo Socrates and Platos as I like to call them possess a train of thought which whistles incessantly but never manages to move beyond the first station,giving a false impression of a locomotive which should/will be departing anytime now.
If you have these sort of people around who mull(or pretend to) over issues, as if they will come out with a solution, so good, they will give a new dimension to the word ingenuity;Watch out!!
You pose them with a trivial problem, they almost magically turn it into a catch 22 situation.
And having said all that we are not dealing with retardation or autism of any sort, in fact these are people who think they know it all, until of course....
