20 June 2006 Dear Mr. Seaton， Thank you very much for taking me with you on that splendid outing to London. It was the first time that I had seen the Tower or any of the other famous sights. If I'd gone alone, I couldn't have seen nearly as much, because I wouldn't have known my way about. The weather was splendid on that day, which I thought was rare. I still remember some people told me that in Britain there was weather and no climate. During the same day, it might snow in the morning, rain at noon, shine in the afternoon and be windy before the night falls. So I think I was lucky. I think the river trip was the best thing of all. London really came alive for me as we saw it from the Thames during that wonderful journey down to Greenwich. It was all tremendously exciting － a day that I shall never forget. Thank you for giving me such a great birthday treat. Yours sincerely, Linda Chen
