     This morning I was going to play outside when my grandfather asked me to drop a letter into a

nearby letter box for him I took over the letter and said goodbye to him. When I passed by a box, I just

put the letter into the box Before long, I got back home. Just then a dustman came into my home with a l

etter in his hand. He told my grandfather that there was a letter for him. He was surprised to see that the

letter was the one that he had written himself. He was wondering about the letter when the dustman told

us that he found the letter as he emptied the litter box Now everything was clear. I had put the letter into

the litter box, not the letter box! How careless I was!
