We spent a day in the country and picked a lot of flowers．Our car was full of flowers inside! On the way home we had to stop at traffic lights, and there my wife saw the bookshelf．
It stood outside a furniture(家具)shop．“Buy it,” she said at once, “We’ll carry it home on the roof-rack(車頂架)．I’ve always wanted one like that．”
What could I do?Ten minutes later I was twenty dollars poorer, and the bookshelf was tied on to the roof-rack．It was tall and narrow, quite heavy too．
As it was getting darker, I drove slowly．Other drivers seemed more polite than usual that evening．The police even stopped traffic to let us through．Carrying furnit ure was a good idea．
After a time my wife said, “There’s a long line of cars behind．Why don’t they overtake(超車)?”
Just at that time a police car did overtake．The two officers inside looked at us seriously when they went past．But then, with a kind smile they asked us to follow their car through the busy traffic．The police car stopped at our village church．One of the officers came to me．
“Right, sir, ” he said．“Do you need any more help now?”
I didn’t quite understand．“Thanks, officer, ” I said．“You’ve been very kind．I live just down the road．”
He was looking at our things：first at the flowers, then at the bookshelf．“Well, well, ”he said and laughed．“It’s a bookshelf you’ve got there!We thought it was…or, something else．”
My wife began to laugh．Suddenly I understood why the police drove here．I smiled at the officer．“Yes, it’s a bookshelf, but thanks again．” I drove home as fast as I could．
