W: In other words, the Romans do what everyone else does. M: Yes, but they do it differently. Everything is different. W: What do you mean? M: Well, the climate is different for a start. It doesn't rain so much as it does in England. The sun shines more often. W: I envy them for the sun. M: I Know. You hate the rain, don't you? W: I certainly do. M: And a Roman really loves life.
