Dear Kelly,
      How's everything going? I   17   in New York City forjust a week, but I'm already in love with the Big Apple. Yoursister Ella   18   me to Central Park and MoMA last Friday.She also told me many stories about those places.
      New York is a modern city, we can see many tall buildingsand artists   19   shows on the street. Guess what? When we   20   along Fifth Avenue yesterday afternoon, we even met asuper star, Taylor Swift. How lucky!
      I've taken many photos. I will show them to you when I   21   back to Taiwan next month.
See you soon,
Lydia
