Both might be right, too. Perhaps the most important thing would be to understand one's options and to consider the situation and whether it would be wise to distance oneself or to come closer. Behind the walls it is possible to make a calm decision based on previous experience, but previous experience might not suit the situation at hand. Human thought processes are mostly the rationalization of emotions. Approaching one's feelings towards a situation helps one to understand one's feelings and to learn what one's rationalization is really based on.
Walls are helpful when the decision has been made and it is time to act.
Problems arise when one does not know his or her own motives but simply does as they have been taught to do. A soldier, who simply does as he was told, prostitutes his own intelligence and individuality when he submits to his commander's thought processes. But if the commander and the soldier would, so to speak, have mental sex with each other and share their feelings, motives and thought processes, understanding would blossom between them. Unfortunately the leaders cannot always create an understanding between each and every one of their followers. This drives people for the lack of better alternatives into thinking like sheep and to intellectual laziness.
