I’ll never forget the day when I went home after school.
It was raining so       (大) that I had to wait for the rain to
stop. But       half an hour it was still raining. Seeing this,
the guard at the gate offered to       (借给) me his umbrella.
I accepted at once. With his help, I got home on time w    
getting wet. The next morning, when I r     the umbrella to
the guard, I said “thank you” to him,       (留) him a note to
express my        sincerely. To my surprise, he said no one had
e     written him to say “thank you”, and it meant a lot to him.
So in my ______, saying “thank you” to others is not only easy
     also meaningful to the person who says it and the receiver!
