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。

　　英國男子Keir Moffatt坐火車回家時偶遇一神秘美女，一見傾心，但苦于無法搭訕，兩人就此擦肩而過。

　　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飽受相思之苦，于是在Facebook上建了一個群。回顧這一段時間的心路歷程，他說：“上周從Cardiff回Bristol的火車上，一個漂亮女孩的出現讓我眼前一亮。”

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

　　“我們幾乎沒怎么說話，她走之后我開始后悔，為什么沒有多跟她聊幾句，不然還有機會約她出去。”

　　"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."

　　“我把這件事告訴了我朋友，他說，有句話很有道理，那就是你只要通過三個人的關系網就能認識一個陌生人。”

　　"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."

　　“半小時之后，也許是一時頭腦發熱，我在Facebook上建了一個群，看是否能通過這個群中的人找到這個神秘女孩。”

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

　　到第二天晚上為止，已經有1000多人加入這個群，然后人數暴增到2000，隨即很快上升至一萬。

　　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萬分感動，于是決定建立一個網站做公益，號召群里的人每人捐一英鎊出來，捐給癌癥基金會。

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

　　他說，由此衍生的公益活動是“一時被感情沖昏頭腦的行為導致的另一種積極向上的結果”。
