只有在我过度劳累的时候，在我长时间不断工作的时侯，在我感到内心空虚，需要充实的时候，我才会感到寂寞。

I'm lonely only when I am overtired, when I have worked too long without a break, when from the time being I feel empty and need filling up.

老头的手轻轻地牵着老妇人那布满皱纹和老皮的手指，这一下子就让那个我原本以为空荡荡的角落充实了起来，我的内心也充实了起来。

The tender caress the old man's hand to his wife's wrinkle and tired fingers, filled, not only what I thought was an empty corner, but it filled my heart too.
