Last night you were at a friend's house. You think you left something important there. Write a note to your friend. Say: what you have left, why it is important, where in the house you think it is. Write 25-35 words. Write the note on your answer sheet.

Hi, buddy. I think i left my phone in your house last evening when we were doing maths. Because i looked all over my apartment and I haven’t found it. I am sure i left it on the shelf in your room. Can you check? It’s important to get it back because I have a lot of information on that phone and the address book of all people I know. Let me know if you’ll find it or not. Thank you.
