Dear Sir/Madam Smith,
It’s Ewelina from Mrągowo.
Do you remember me?
Last summer I lived at your home, during my stay on course of English language.
At first I want to send my greetings to all family. I spent in England wonderful times. I want to say thank you for all what you did for me. My travel wasn't very long because during flight I read a book so flight pass me guickly . On airport took me back my longing parents.
My parents say hello and send you greeting. I am writing because I like you to visit Poland. I`m already making plans for this trip and maybe you can will arrive to us in the closest winter holidays. It would be great. I can show you some interesting places. The best place which I want you to see is Cracow. It`s very beautiful city in south Poland. It is very old city so there is many monuments. In the center of city there is a famous market. We can visit an old church, where is Wit Stwosz`s altar. We can also visit an old castle called "Wawel". I think it is worth seeing because this places are very famous and they show the history of Poland.
I`m already making plans for this trip and I think you could come to me next week.
I`m looking forward to your reply and I hope I will see you soon.
See you soon.
