记得小时候，经常与邻居的孩子打架斗殴，不过过了几天，大家又和好如初了。这让我想起的一个习语：clean slate

slate是石板的意思。将石板擦干净，不就是clean slate了吗？所以该习语的是指一笔勾销，忘记过去重新开始。to start fresh despite past mistakes or problems

I know we've had our differences, but I'd like to repair our friendship. Can we start over with a clean slate. (这句话大概意思是我知道我们存在分歧，但我们可以不计前嫌，和好如初吗？)

I really appreciate you giving me a clean slate after I failed my first test.

Let's forget our quarrel and start again with a clean slate.

也可以表示某人或某事在经历某种失败，挫折或灾难之后，重新开始。

After a decade of gambling, I am going to start my thirties with a clean slate.

The previous negotiations did not go anywhere, and we intend to start them again next week with a clean slate. (这里的didn't go anywhere是指谈判没有取得什么进展)

After the earthquake/ bankruptcy, I am looking forward to starting off/ over with a clean slate.
