Conversation:

A: Hello, Hanson. Today I come to say goodbye to you, for I'm going back to London tomorrow.

B: No, not so soon. Couldn't I persuade you to stay a couple of days more?

A: Much as I wish to, but I really can't. I've already booked the flight.

B: I hope this won't be our last meeting.

A: Of course not. You can come to London to visit me in future, and I also will come here if I have a chance.

B: I'll Miss you.

A: I'll Miss you too. You are really a good friend.

B: It's a pity that I'm too busy to see you off tomorrow.

A: It doesn't matter. 

B: Take care of yourself and remember to keep in touch.

A: I will.

B: Goodbye and have a good flight.

A: Thank you. Goodbye. 

Translation:

你好，汉森，今天我是来向你道别的，因为我明天就要回伦敦啦。

不是这么快吧？我不能说服你多留几天吗？

我也很想，但是真的不能，我已经订好票了。

我希望这不是我们最后一次见面。

当然不会，你以后可以来伦敦找我，而且我一有机会也会来这里的。

我会想念你的。

我也是，你真的是个很好的朋友。

很遗憾，我明天太忙，无法给你送行。

没关系。

自己保重，记得要常联系哦。

我会的。

再见，祝您一路顺风。

谢谢你，再见。
