Dear Ken,
 Sorry it's been so long since I last wrote, but I've been too busy preparing for my exams.
My city is San Paulo. It is biggest and noisyest city in Brzil. Is not very well fot tourists is more commercial city. Also it have very much traffic and pollution. Maybe London have the same. I like San Paulo entertainment. You can find goods bars and restaurans.
 My friend Toao he came in London the last year and he has gone to the theatre see ''The Buddy Holly Story''. He say me it was wonderful.
