If time could stop at the moment when we first met.

人生若只如初见。

清 · 纳兰容若《木兰花令·拟古决绝词》

Rather than leave them to moisten each other with their damp and spittle， it would be far better to let them forget themselves in their native rivers and lakes.
相濡以沫不如相忘于江湖。

《庄子》

I only pray our life be long, 

And our souls together heavenward fly!

但愿人长久，千里共婵娟。

北宋 · 苏东坡《水调歌头》

By the window shut,
Guarding it alone,
To see the sky has turned to black!

守着窗儿，独自怎生得黑？

And the drizzle on the kola nut

Keeps on droning:

Pit-a-pat, pit-a-pat!

梧桐更兼细雨，到黄昏，点点滴滴，

Is this the kind of mood and moment

To be expresses
By one word "sad?"

这次第，怎一个，愁字了得。

宋 · 李清照《声声慢》

Oh, I cannot say it is not endearing,   Only, when the west wind stir the curtain,   I see that I am more gracile   than the yellow flowers.   

莫道不消魂，   帘卷西风，   人比黄花瘦！

宋 · 李清照《醉花阴》

But in the crowd once and again I look for her in vain. When all at once I turn my head, I find her there where lantern light is dimly shed. 

众里寻他千百度，蓦然回首， 那人却在，火阑珊处

宋 · 辛弃疾 《青玉案 元夕》 

If you entered my deep mood of longing,

You would understand my suffering for yearning.

入我相思门，知我相思苦 。

唐 · 李白《秋风词》

When the moon hung behind the willows, 

Young people went out on dates under them. 

月到柳梢头，人约黄昏后。

宋 · 欧阳修《生查子 元夕 》

"Fair fair"cry the ospreys,

On the island in the river .

Lovely was the noble lady ,

Fit bride for our lord.

关关雎鸠，

在河之洲。

窈窕淑女，

君子好逑。

《关雎 》

上邪，

我欲与君相知，

长命无绝衰！  

By heaven, 

I shall love you, 

To the end of time! 

山无棱，

江水为竭，

Till mountains crumble, 

Streams run dry, 

冬雷震震，   

夏雨雪，      

Thunder rumbles in winter, 

Snow falls in summer, 

天地合，

乃敢与君绝。

And the earth mingles with the sky, 

Not till then will I cease to love you!

《上邪》
