Parents always live a less pure life than their children, because they condone everything they do. The ability to condone everything in oneself but practically nothing in one's children is the boon that "experience" bestows on humanity. What parents call experience is really nothing but attempts, successful to the point of sheer cynicism, to belie everything which they found pure, true and right when they were young. They themselves don't notice the awful cynicism behind this incessant talk of "experience" being the highest aim in life: they only notice "inexperience" in their children, that is, the form of inexperience called purity and integrity, and then they get annoyed.
