Hector works in a clothes store. The store is kind of far from his home and he usually gets to work by bike. In fact, he goes almost everywhere by bike. Do you know why? His feet aren’t so good. His left foot is much bigger than his right foot. It makes it difficult for him to buy right(合适的) shoes.

One day, his bike was broken(坏的). He had to walk to the store. When he arrived, it was nine-thirty. His boss(老板) Mr Dean was very angry because  he was an hour late.

“Why are you so late today?” asked Mr Dean.

“I’m sorry, but my bike is broken and I have to walk. You know, my right shoe is too big for me...” said Hector.

“Why not buy two pairs of shoes in different sizes. Thus you can get the right shoes for you.” Mr Dean said.

“I know. But it’s too ugly.” said Hector.
