Dear Robin,
I am writing an answer to your email. I read that you are going to a sports camp with your friends in the mountains. I would really appreciate going with you and your friends. It is a great opportunity to enjoy our holiday actively. I know you like sports as well as I do, it will be the best solution to go there. As you know, I have been playing ice hockey for many years. Ice hockey or football (soccer) are team sports and I would like to play at least one of these with you there.
As you know I like spending time in nature [note]. I know you are also a curious adventurer, so it will be better for us to take some tents and enjoy our time in the country. Could you ask your friends what kind of accommodation they prefer to take it? A traditional food in the Czech Republic is goulash with dumplings. I have to tell you I haven´t cooked it many times. But it will be a pleasure to cook for ourselves.
It might be best to fly a few days before and stay in your apartment. We could go on some trips and do some sightseeing and I would like to find out about your country, culture and habits as soon as possible. I look forward to reading your answer!
