I fell in love with England because it was quaint （古雅）— all those little houses, looking terri­bly old-fashioned but nice, like dolls’ houses. I loved the countryside and the pubs, and I loved London. I’ve slightly changed my mind after seventeen years because I think it’s an ugly town now.

Things have changed. For everybody, England meant gentlemen, fair play, and good man­ners. The fair play is going, unfortunately, and so are the gentlemanly attitudes and good man­ners — people shut doors heavily in your face and politeness is disappearing.

I regret that there are so few comfortable meeting places. You’re forced to live indoors. In Paris I go out much more, to restaurants and nightclubs. To meet friends here it usually has to be in a pub, and it can be difficult to go there alone as a woman. The cafes are not terribly nice.

As a woman, I feel unsafe here. I spend a bomb on taxis because I will not take public trans­port after 10 p. m. I used to use it, but now I’m afraid.

The idea of family seems to be more or less non-existent in England. My family is well united and that’s typically French. In Middlesex I had a neighbour who is 82 now. His family only lived two miles away, but I took him to France for Christmas once because he was always alone.
