 Person1:      Do you think advertising has an influence on the choices you make when you're shopping ?  
 Person2:  I guess so . I usually buy name-brand clothing , shoes , and electronic goods . How about you ?  
 Person1:      I actually try to avoid name-brand items . I can't stand it when big companies advertise their products all over the place !  
 Person2:  I know that advertisers are experts at persuading people to spend their money , I think brilliant items are usually higher quality than ~ grounds .

 Person2:  What do you think about the " impossible is nothing " billboard on the high street ?

 Person2:  I think it's a brilliant advert ! It really grabs my attention !  
 Person1:      To each their own !
