You were very kind. You brought out all your jewellery and you told me I could take anything I wanted. There were so many beautiful things that it was hard to choose. And then I saw a lovely diamond necklace with a big blue stone in the centre.

你太好了。当时你把所有的珠宝首饰全都拿了出来，而且说，我要什么就可以拿什么。漂亮的首饰太多了，实在难挑选。后来我终于看中了一条美丽的钻石项链，中间还嵌着一颗大蓝宝石。
