     Dear Dr Jackson,
          My parents are never happy with me. They are always criticizing (批评) my clothes, my hair and
the music I listen to. They hate my friends'looks and they keep complaining when I go with them. I'm
not allowed to stay out as late as my friends do, so I can't have any fun. My parents only seem to care
about my school marks. Although I love them, sometimes I feel we live in different worlds. If they love
me, can't they understand me? How can I make them understand me?
Angel
     Dear Angel,
         Your problem is common (共同的) to both teenagers and parents. Don't worry, because all this is
natural. You see, your parents have grown up at different times and they have different experiences (经历).
So they think some things are strange, but you find the same things ordinary. For example, the music you
like may sound like noise to them. Your parents love you, so they feel they must protect you from anything
bad or strange. On the other hand, you don't want to be different from other teenagers, so you feel that
your parents restrict you.
        I think you should talk about this problem with your parents. Try to explain to them what you want
and let them know they can believe you. Sooner or later, they'll find you are a responsible (有责任心的)
person and they will give you more freedom (自由).
