昨晚约摸半夜的时候，他和我坐在厨房里，默默无言，这时希斯克利夫回来了。

Many famous people discovered important things when they were just sitting silently by themselves...you know the story about Isaac Newton, right?

许多名人在自己静静地坐着时发现了重要的事情… … 你知道艾萨克·牛顿的故事吧？

Now, I've written here: " to strike a balance" , that means not talking too much, but not also sitting silently staring into the mirror, which is a little bit sort of unfriendly.

现在，我在这里写了：“保持平衡” ，意思是不要说太多，但也不要静静地坐着照镜子， 这有点不友好。
