However I must say that if one is not very interested in archaeology or in architecture a two days visit would be enough. Unfortunately we had only one more day in this beautiful country. The books had cost only two or three dollars, cheap even for second hand books and after buying them I discovered that these were actually copied books and not used books. It was too late. I think I have to switch back to English. It will take me two years until I write an entire letter in German and I suppose I do not have the time for it. Does that mean that I am not serious about learning?
