Why is it easy to walk along a school corridor without bumping into the walls, but it would seem really tricky walking along a cliff ledge, which was the same which was the same width?

Fear is difficult to overcome. You are constantly thinking about what could happen or what will happen, that it doesn't matter the width of a cliff ledge or school corridor; it will always be easier to walk a school corridor. Ask yourself this: Would I rather walk on the edge of a cliff, where I could fall, or along a school corridor, where I could bump into walls? The answer should be simple. A school corridor, no der. Now ask yourself why. I would say, "Well, bumping into a wall is a lot better than falling off a cliff!!"

Because of your fear that you just might fall off the cliff makes it a lot harder to walk along a cliff ledge than a school corridor, no matter the width.

i got you covered.. i will do my best

the speech this question is referring to is president kennedy's special message to the congress on urgent national needs, may 25, 1961

kennedy responds in a very direct and concrete way to those thinking that communism is a positive system:

"yet their aggression is more often concealed than open. they have fired no missiles; and their troops are seldom seen. they send arms, agitators, aid, technicians and propaganda to every troubled area. but where fighting is required, it is usually done by others--by guerrillas striking at night, by assassins striking alone--assassins who have taken the lives of four thousand civil officers in the last twelve months in vietnam alone--by subversives and saboteurs and insurrectionists, who in some cases control whole areas inside of independent nations." (kennedy)

president kennedy presents communism as cowardly, as a hidden and treacherous weapon that strikes from the shadows like thieves, he represents the system as not even being capable of showing and open and overt attack or confrontation. to finish up the response, he expresses that the system attacks even a country's idependence and freedom.
