But my brother will never know what it feels like to have a mind that isn't an ocean whose depths are clear to the very bottom, but a bog in which I wander, lost and lonely.

但我弟弟永远不会知道另一种感觉——你拥有的头脑不是一汪清晰见底的海洋，而是一片雾茫茫的荒原，失落、孤独。我弟弟当然不会懂得这种感觉。

But it is very clear in my mind.

但是却清晰的出现在我的脑海中。

Patches sof white clouds in the blue sky are my slight gloom for our parting, but then my mind broadens like the clear sky at the prospect to re-gathering.

蓝天上的缕缕白云，那是我心头丝丝离别的忧愁，然而我的胸怀和长空一样晴朗，因为我想到了不久的重逢。
