I have found it quite different here from China since I came to the United States .   What's the difference ?   Some friends of mine took me to the mall to go shopping . It was so big . I think I could get lost if I went there alone .   You must have bought many things in the mall ?   Not really many . I was told that on weekends there were always the flea markets , so I decided to come to the flea market to buy a bargain .
