Today , I found out something about my brother that could get him into a lot of trouble. I’ m not sure whether to tell mum and dad.

Although william and I are almost 18 , 1.妈妈和爸爸仍然对我们要求很严格。Recently , William has begun wearing some strange clothes, and he looks quite different from before.2.The other day I saw him smoking in his room , with two of his friends, Jack and Sean .3.I know mum and dad would be angry with me if they knew that I had kept this secret for them . 64.也许我应该告诉他们, so they would’t blame me for keeping a secret.4.However, I don’t think william will live at home for much longer as he’s planning to go to university soon, 5.His grades are still good. It seems that his behaviour hasn’t hurt his studies . Maybe I should just keep my mouth shut.what should I do?
