Dear Tom,

How time flies! We will have to say goodbye after a week, but I will never forget the beautiful days when we spent together. In my memory, you are such kind a person that you will always offer me help wherever I get into trouble. You are the most considerate person who know exactly what I need in our class.

Do you still remember that night twenty years ago? When I suddenly fell ill, you carried me to nearest hospital. Moreover, you attended to me careful while I was staying in hospital. Later, you managed to help me with my lesson. Without your help, I can not have passed the exam. Though we are parting soon, but I will keep the favors you’ve ever done me in mind.

Best regards
