Analogy

A decent analogy of a person.
You get up to sharpen your pencil, yet the lead continues to fall out. Does this mean that the pencil is attempting to piss you off? Does this mean that the pencil should be thrown away and replaced by a pen?
For a Person:
Yes you will have many bad days, many countless disappointments, and many times he or she will fail you in some way. Does this mean this person is bad, attempting to piss you off in some way, or should you forgo the formalities and replace this individual with that of a robot or even worse cut yourself off from any and all interactions with people?
I believe that it just means that when cohesion and harmony are achieved it will be an even sweeter and longer lasting due to it will hold the most meaning.
