Analysis of the methaphor "Life is like a box of chocolates"

'Life is like a box of chocolates...' At first glance the quote 'life is like a box of chocolates seems' rather silly. How could such a large and complicated concept such as life be compared to something as small and simple as a box of chocolates? There have been two opposing viewpoints in regards to the meaning of this quote, and each viewpoint comes about by a different analysis of what life and chocolates …

…in a cabinet. They will get eaten if someone shows desire, but it's not important. Under this interpretation, life is pointless and merely for show. People don't do things because it is what they feel that they should, people do things because they are expected to (just as the lover is expected to give chocolate). It is better to put up an lofty facade, then to be true and honest to the people around you.
