Patrick White said this quote

I would like to believe in the myth that we grow wiser with age. In a sense my disbelief is wisdom. Those of a middle generation, if charitable or sentimental, subscribe to the wisdom myth, while the callous see us as dispensable objects, like broken furniture or dead flowers. For the young we scarcely exist unless we are unavoidable members of the same family, farting, slobbering, perpetually mislaying teeth and bifocals.
