A few years ago I had purchased another car since my old one was not going to last long. 
几年前我的旧车不能用了,我就买了一辆新车。

I still had my old car and had not gotten rid of it yet when this happened.
但那时我还留着旧车,没有把它处理掉。

Each day I would drive to the next town and park my new car in a residential area and walk a few blocks to get to work.
每天我都会开车去旁边的镇上,把新车停在一个居民区,步行几条街去上班。

On the way, I noticed this one car that was identical to my old car except for different color and that it also had one missing hub cap.
在路上,我注意到有一辆车和我的旧车一样,就是颜色不同,那辆车也掉了一个轮毂盖。

One morning that week, I took a hubcap off of my old car and put it on this car that needed one and walked off.
那个星期的一天早上,我从我的旧车上卸下来一个轮毂盖,安在了这辆需要它的车上,然后离开了。

I never saw the owner and the owner never saw me.
我从未见过那辆车的主人,他也从未见过我。
