B: It doesn't matter.

A: Really sorry to have kept you waiting.

B: That's quite alright. What made you so late?

A: Well, when I was leaving, I just couldn't find the key to the door. I remembered that I put it on a table, but I just couldn't find it.

B: Did you find it at last?

A: No. My wife just came back and I rushed out of the room.

B: It's so fortunate for both you and me. Otherwise, I would still be waiting.

A: Definitely. To make it worse, the bus I took broke down halfway.

B: How did you come here? Change to another bus?

A: No. I got the taxi. Otherwise, I'd still be on the way.

Translation:

真抱歉，我来晚了。

没关系，真不好意思让你等我。

真没关系，你怎么会这么晚呢？

后来找到了吗？

没有，我妻子正好回来了，我就赶紧冲了出来。

对我俩来说都很幸运，要不然我现在还在等着呢。

是呀。更糟糕的是，我乘的那辆车半路上坏了。

那你怎么来的？换了一辆车吗？

没有，我是打车来的，要不然我还在路上呢。
