John , did you have a dream when you was a little boy ?   Of course I did . I dreamed to be a pilot when I grow up . But unfortunately , I didn ’ t realize it .   I had the same experience with you . When I was a little boy I dreamed to be a great scientist . But now you see , I'm just a common office clerk .   Okay , forget about that . S , do you have some practical dreams at present ?
