SILENCE. Speak not but what may benefit others or yourself; avoid trifling conversation.

We must be free not because we claim freedom, but because we practice it.

在故事中，沉默可以和文字一样有力。

I love man as my fellow; but his scepter, real, or usurped, extends not to me, unless the reason of an individual demands my homage.

可持续性不仅仅是植树造林；而是确保我们今天采取的每一个行动都不会损害未来。
