把这九句话翻译成英文。谢谢。（不要太生硬了。）

1）曾经以为是这样。

I had once thought that this was the way of it.

2)的确，简单是一种快乐。

Really, simplicity is a joy.

3）我问，什么回忆最可怜，是不是在很久很久之后，想很久以前。

I am asking, what kind of remembering is most deserving of pity, is it thinking about a long long time ago when a long long time has past.

4）也许我该忘了这一切。
Maybe I should forget it all.

5）走了那么久才发现，才发现在原地打转。

After having left for such a long time, I only realized now that I have been going in circles back to where I started.

6）解释爱死无聊的事情，有些过去一直还没过去，有些人在心里的心里，以为不在相信真爱无敌，以为可以一个寂寞来麻醉自己。
It is pointless to explain love, some are past and some are not, someone is in the heart of hearts, not believing in the invincibility of true love, thinking to numb my pain with loneliness.

7）我会多疼你一点。
I will treat you more tenderly.

8）属于我的快乐。
Happiness that are mine.

9）忘了那些同让一切归零吧

Let bygones be forgotten
