Keir Moffatt, from Bristol, was travelling home from Cardiff at 7pm on May 6. Onboard he saw a girl with a blue hair band, sparking the beginning of the search。

　　英国男子Keir Moffatt坐火车回家时偶遇一神秘美女，一见倾心，但苦于无法搭讪，两人就此擦肩而过。

　　Chronicling his quest on the website he wrote: "On the train back to Bristol from Cardiff last week, a gorgeous girl in my carriage really caught my eye."

　　回家之后，Keir饱受相思之苦，于是在Facebook上建了一个群。回顾这一段时间的心路历程，他说：“上周从Cardiff回Bristol的火车上，一个漂亮女孩的出现让我眼前一亮。”

　　"We barely spoke but, when she left, I regretted not speaking to her more - and asking her out."

　　“我们几乎没怎么说话，她走之后我开始后悔，为什么没有多跟她聊几句，不然还有机会约她出去。”

　　"When I was driving home with my mate, I mentioned my regret and he said, Well, you know what they say, you're never more than three people away from who you want to know."

　　“我把这件事告诉了我朋友，他说，有句话很有道理，那就是你只要通过三个人的关系网就能认识一个陌生人。”

　　"Half an hour later, and perhaps against my better judgment, I set up this Facebook group to see if my mate's theory was true - to see if I could find the Mystery Train Girl and get a second chance to ask her out."

　　“半小时之后，也许是一时头脑发热，我在Facebook上建了一个群，看是否能通过这个群中的人找到这个神秘女孩。”

　　By the following evening more than 1,000 people had joined the group, which soon swelled to 2,000, and then 10,000 members。

　　到第二天晚上为止，已经有1000多人加入这个群，然后人数暴增到2000，随即很快上升至一万。

　　Mr Moffatt then decided to put the interest to use, setting up a JustGiving web page, asking his followers to donate £1 to Marie Curie Cancer Care。

　　Moffatt万分感动，于是决定建立一个网站做公益，号召群里的人每人捐一英镑出来，捐给癌症基金会。

　　Raising money from his adventure would be "a potentially wonderful outcome to an otherwise rather embarrassingly self-indulgent quest," he reasoned。

　　他说，由此衍生的公益活动是“一时被感情冲昏头脑的行为导致的另一种积极向上的结果”。
