Dear Peter,
I feel so sorry to be told that you've been addicted in smoking.
As we all know,smoking is harmful to the smokers' health,what's worse,it may cause the lung cancer,and many people die for it every year.Therefore,as you are so young and have not developed your smoking habit,you should give up smoking as soon as possible.In fact,to quit smoking is not that hard,as long as you have the insistence,I believe that you will make it.By the way,I want to tell you the importance of health,which is the basis of anything.And losing health means losing everything.
Therefore,I hope that you can accept my advice for I will never do harm to you,and I also hope that you can live a better life.
Yours
****
