Young people have bought things that aren't necessary.However,They always feel that they one trendy .
On the one hand, The boys don't do so many in changes the style and they buy less things. Moreover They visit a lot of shops.
On the order hand, The girls buy incotrolatly things that they don´t need in their better houses. Moreover, The girls have better liked than the boys.
Secondly, The girls spend more money with bigger addiction.
In short, My reason is that young people don't have to buy in the shops.
