It is an illusion that youth is happy, an illusion of those who has lost it.
Illusions are like umbrellas - you no sooner get them than you lose them, and the loss always leaves a little painful wound.
What do we any of us have but our illusions? And what do we ask of others but that we be allowed to keep them?
It is dangerous to let the public behind the scenes. They are easily disillusioned and then they are angry with you, for it was the illusion they loved.
