Man's youth is a wonderful thing: it is so full of anguish and of magic and he never comes to know it as it is, until it has gone from him forever. It is the thing he cannot bear to lose, it is the thing whose passing he watches with infinite sorrow and regret, it is the thing whose loss with a sad and secret joy, the thing he would never willingly relive again, could it be restored to him by any magic.
青春奇妙无穷，充满魅力，充满痛楚。青春年少的时候根本不知青春为何物，直到青春一去不复返了才对青春有了真正的认识。谁都想让青春永驻，不忍青春离去； 眼睁睁地看着青春流逝,心中会涌起无穷的忧伤和惋惜；青春的失去是人们永远感到悲哀的事；青春的失去是人们真正觉得悲喜交集的事；即便奇迹出现青春复苏， 谁都不会心甘情愿重度青春的岁月。
