Some details in life may look insignificant but appear to be vital leitmotifs in a person's life. They may have the value of "Rosebuds" of Citizen Kane or "Madeleine cookies" of Marcel Proust or "Strawberry fields" of the Beatles. People regularly walk down the memory lane of their early youth. The paper boats of their childhood are recurrently floating on the waves of their mind and bring back the mood and the spirit of the early days. They enable us to retreat from the trivial, daily worries and can generate delightful bliss and true joy in a sometimes frantic and chaotic life. ("Paper boats forever" )
