M: Margret! Long time no see. Where have you been these days?
W: I’ ve been to London for a couple of days.
M: Oh, have you been there on business?
W: No. Actually I went there for a break with my mother.
M: You must have a wonderful time there.
W: Very wonderful indeed. London is a pretty place with spectacular palaces and nice parks. There are so many things to see and we got up very early every morning and slept very late. It was rather tiring for my mother.
M: Did you see the queen?
W: I got a glimpse of the queen when she passed by. They were so many people and I hardly saw her face. But the most unbelievable thing is that I met Benedict Cumberbatch by chance. I even took a photo of him. Can you imagine that?
M: God! I wish I were you.
