Spwawdźcie, czy nie ma błędów.
I am sorry that i hane not written before, but i was in Spain lat week, and I have a lot of paperwork to do. I want to thank you very much for invitation. I am very happy that you still remember me. Unfortunately i must apologise you because I can not attend in our ceremony. Firstly i have a new job, and I want to do a good impression in my boss, so I think that taking a fulough is not a good idea. My next reason is fact that i must look after my small sister who has pneumonia. I am sad, because i waited on this ceremony a long time. I hope that you will have a good time and you will send me new phots.
