Текст: 
 Dear Mr Leman 
 I thought I'd drop you a line to say thanks for your kindness and generosity. I never forget chatting with you. 
 Not without reason you got the title "Chef of the Year". The best thing was a soup with prawns. My sister is going to become a chef, and she like to get recipe of this. 
 I had knew only 200 words before I began chat with you. I still remember how I wrote dictation and remember this with smile. Your stories helped me to improve the language. 
 I hope we will meet again. Thanks a million.
