Q: Person1: So , you friend ' s getting married on Saturday . What have you bought her as a wedding gift . I find is so hard to choose the right gift .
Person2:My friend and her fiance had a really good idea . They have cut out pictures from catalogues and pasted them in a notebook . The picture are of things they want . People sign their name by the item they will buy .
Person1: That ' s clever ! Then everyone knows that they are buying something the couple really want and there ' s no chance of two people buying the same gift . What things were in the notebook ?
Person2:Most of the things were household appliance . You know , everything from an iron through a vacuum cleaner to a cooker . I think it ' s an excellent way for everyone who knows the couple to help them set up home .
Person1: So , what did you get them ?
Person2:I bought a sewing machine . I know that my friend likes making her own clothes , but her current sewing machine is quite old and has some problems .
Person1: What ' s wrong with it ?
Person2:She says that after several years of use , it ' s not working properly . When she uses it , it makes a funny noise .
Person1: Household appliance don ' t seem to last for a long time nowadays .
Person2:I think it ' s because the manufactures are constantly bringing out new models . Because they know that we will buy the new models , the appliances don ' t need to last more than five or ten years at most .
