It was the first time that I had seenthe Tower or any of the other famous sights. If I'd gone alone, I couldn't have seen nearly as much, because I wouldn'thave known my way about.The weather was splendid on that day, which I thought was rare. I still remember some peopletold me that in Britain there was weather and no climate. During the same day, it might snow in the morning, rainat noon, shine in the afternoon and be windy before the night falls. So I think I was lucky。
