Life is like a box of chocolates.
Sometimes there are nuts in them.
Some people are allergic to nuts.
Some people boycott the presence of the nuts because they pose a threat to the lifestyle of those people who are allergic to them.
Some people then attempt to divide the chocolates into two classes: the nutty and the normal.
But no matter how hard they try (and they do try so very hard), you realize the box of chocolates may always contain traces of nuts.
Similarly, life is like a box made of chocolate.
People spend so much time focusing on their outside it takes them a while to realize they're hollow.
