Hi Jean-Paul,

How are you? I’ve just finished doing my homework, so I have a lot of free time. Yesterday I decided to start reading “Harry Potter and Chamber of secrets” book. It’s really exciting! Besides, it has a lot of plot twists. So that’s why I highly recommend you to read it! Not only that, I decided to start doing juggling. I should say it’s really hard. I saw some street jugglers last summer. They were doing it amazingly, so I decided to study it. Hopefully there’s enough time now!

See you on Saturday
