Informal letter (email for Jonh)

To: Jonh Brown
From: Matvey Petrykin
Subject: Sailing lessons
Hi, Jonh,
I read your advertisement for the sailing lessons and I’d love to come on the sailing with you.
However, I would like to ask you a few questions about it. First of all, how much does the lessons cost? Also, where exactly is the sailing place? Secondly, your advert mentions some of the activities we will take part in on the lessons, like  free-swiming. What else can we do? If I can, I want to try a windsurfing. Also, will I need to bring any special clothes or equipment with me? Finaly, I'm 13 years old. Do you need a consent of my parents?
Thank you very much for your time.
Can’t wait to hear from you.
With best regards,
Matvey Petrykin
