Joseph Emmons is blind.He has a trained dog called Buster that leads him to where he wants to go.Buster is a Seeing Eye dog.Although Mr.Emmons has a handicap (生理缺陷),it isn’t a big problem.He has a helpful job and he earns his own money.Mr.Emmons sells brooms (扫帚) to people in this part of the city.He has worked every day except Sunday for forty years.After his breakfast,Mr.Emmons holds Buster,carries brooms and sells from house to house.People choose a broom and they pay him while Buster sits and waits beside his master.It takes four and a half months to walk to every house in this part of the city.So Mr.Emmons visits each house every four months,and by then people are usually ready to buy new brooms.But these days he has a problem.His brooms last so long that sometimes they are still good after four months.Then nobody needs to buy a new one.Mr.Emmons likes his job and is proud of his brooms.He picks up a new supply of brooms every week.He says,“If you don’t sell people something good,they’re not going to buy from you the second time you come around.”
