Everybody here is very kind to me,but there are times when I think of home and get rather sad.I sometimes get a little tired of English cooking.I go to school once a week.School is a part of London where there are all sorts of restaurants,French,Italian,Greek,Spanish,Indian and Chinese.So when I'm tired of English cooking,I go to one of the school restaurants.
Sometimes I even have a bottle of wine!Wine isn't cheap in England.It isn't something we drink every day.English people do not talk as much as we do.I've often traveled by train and nobody has spoken to me during the journey.I know one Englishman who is unusual.He speaks seven languages.He can also be silent in seven languages!But I've found one way to make him talk.He's interested in mountain climbing.If I ask him about climbing,he's always ready to talk.
