There is a Charlie Brown episode where they are taking a math test and peppermint patty asks marcie what she wrote for a certain question. Marcie replied with a number (I don't remember which) and peppermint patty says, "I wrote green" Green? Was the surprised response. She replied, "I thought it was a trick question."
People sometimes complicate simple things for no reason. It isn't because they are less intelligent or are missing something, it's because they think that life is more complicated then it really is.
On the other hand, sometimes people take things that are very complex and try to provide a simple solution that doesn't fully answer the need.
Therein lies the problem.
