The two lovers swore to love each other for eternity.

两个恋人发誓永远相爱。

There will always be things I will never learn, I don't have eternity before me!

If there's something more terrifying in the world than eternity, then it's probably the current progress of my diploma thesis.

如果有什么比以往任何时候在世界上可怕的，它是我的论文目前的发展。

Never knew before what eternity was made for. It is to give some of us a chance to learn German.

以前從來不知道永恆是為了什麼。它是為了給我們一些機會學習德語。
