Polecenie: An English person recently came to your school to give a talk (what was the talk about?). He/She left a personal possession (what is it?) at the school (where exactly?). You want to return the possession (how will you return it?) but you have had difficulty contacting the person (how have tried to contact him/her?). You have a possible address for the person, but you're not sure if it's correct (why?).
Write a letter to the person.
1. Thank them for coming to give a talk.
2. Explain the situation.
3. Ask them to contact you.
Praca: Dear Sir or Madam
I am writing in connection with your last visit in our school. Firstly I want to thank you for your coming and lecture. You was giving a talk about aggression among young people. We find your personal possessions: calendar and some keys in lecture hall. I want to return the possessions by sending them by registered post, but it is difficult for me to contact with you. I tried to phone to you on a number of occasions but the number I find in the Internet was unobtainable. I have got some your address but I have doubt if it is correct because I think it is incomplete.
Could you contact me as soon as it is possible to confirm an address, please?
Yours faithfully
