Why did Maria go to the Oxford Street?

W:  Hi,  Jason.
M:  Hi,  Maria.   You look excited.   What’s up?
W:  I had an amazing day.
M:   Really? Whal happened?
W:   I was shopping down the Oxford Street when I saw a woman.   She looked really familiar.   I mean 1 was sure I knew her.   She was bonding down and looking around her for something.
M:   What was she looking for?
W: She was looking for her ring. Anyway, I found it for her. And when she got up, I realized it was Susan Hill,   the famous actress.
M:   You mean the Susan Hill in the Good Old Days? You can’t be serious.
W:  Believe it or not.  Anyway,  she was really grateful and she gave me a ticket to her new play. It’s worth 50 pounds.
M:   Wow,   that’s great.
W:   I know,   and she invited me to have dinner with her after the play with other actors.
M:   You’re really lucky.
W:   So are you.   She said 1 can bring a friend.
M:  Gosh!  Thank you,   Maria.
