An e-mail to Mary
Hi, Mary!
How are you? I miss you so much!
I arrived in Rome last week and I’m having a lot of fun. This morning my parents and I woke up at 8:00 and had a great breakfast at the hotel. Afterwards, I walked a little and saw many tourists (many from Russia and China) and even some famous people!
Now we are going to Venice.
How are things in Las Vegas? Come meet us!
See you soon!
Paul.
