Nobody Likes That

Someone once told me that everything in life is coincidental, that everything that people notice is what they want to notice and make those events and words what they want them to be. There is no fate, there is no God, merely events, and the improper analyzation and interpretation of them. People's heads are clouded with concepts like fate, and freedom, and love. But why is it that some couples marry with no intent of reproduction if all of this is about offspring?
