Dear ...(если там имя есть у друга этого, то вписать его сюда),
 Of course I have seen all the photos you took, they are wonderful! I also love taking pictures, it's one of my hobbies. I always thought that taking pictures is the best way to keep your memories.
Last holidays I spent in a countryside near my hometown. It's a very beautiful place, it's surrounded by beautiful meadows and woods. Also there is fantastic sky with million stars that I enjoy looking at during night. I was going to swim in a nearby river every day, it's one of my all time favorite activities! Swimming makes me feel very happy.
I guess I'd say that I like summer holidays more. Winter holidays are also nice because of Christmas and snow, but there are much more interesting things I can do during summer. 

Best wishes,
(твое имя :)
