Input: Consider Input: Article: London--A morning's train ride away, across the Channel, English kids talk about Liverpool's soccer team in a Paris puB.Some Parisians have even started to go to work in London.In the 19thcentury, Charles Dickens compared the two great rival cities, London and Paris, in " A Tale of Two Cities".These days, it might be A Tale of One City. Parisians are these days likely to smile in sympathy at a visitor's broken French and respond in polite English.As jobs grew lack at home over recent years, perhaps 250,000 Frenchmen moved across the Channel.With an undersea tunnel, they could travel between cities in three hours.The European Union freed them from immigration and customs. Paris, rich in beauty, is more attractive.But London feels more full of life, and more fun until the pubs shut down. "For me, the difference is that London is real, alive," said Trevor Wheeler, a banker. Chantal Jaouen, a professional designer, agrees."I am French, but I'll stay in London," she saiD. There is, of course, the other view.Julie Lenoux is a student who moved to London two years ago."I think people laugh more in Paris," she saiD. In fact, London and Paris, with their obvious new similarities, are beyond the old descriptions.As the European Union gradually loosened controls, Londoners _ into Paris to shop, eat and buy property . "Both cities have changed beyond recognition." Said Larry Collins, a writer and sometimes a Londoner.Like most people who know both well, he finds the two now fit together comfortably. "I first fell in love with Paris in the 1950s and it is still a wonderful place," Collins saiD."But if I had to choose, it would be London.Things are so much more ordered, and life is better." But certainly not cheaper.In fancy parts of London, rents can be twice those on Avenue Foch in Paris.Deciding between London and Paris requires a lifestyle choice. Like Daphne Benoit, a French journalism student with perfect English, many young people are happy to be close enough so they don't have to choose. "I love Paris, my little neighborhood, the way I can walk around a centre, but life is so structured," she saiD."In London, you can be who you want.No one cares."

My first thoughts in the morning were of you. When I got home from work, I couldn't wait to see you. I liked talking to you very much and I wanted to know what your day was like. You kept my spirit alive, my mind challenged and my body active. You were, and still are, the light of my life. Without you, my life would have been boring. You made me happy and you continue to do so. You are a mother now, with a child of your own. I know you love her, so I think you should tell her how happy she makes you.
