for an advice. This is a secret, so don't tell anybody else.  
My cousin and I used to getting along very well and          
we were good friend. We were planning to spend                
part of the winter holiday together, so now                
I don't think I want to invite her home.                      
Recently I has discovered that he's started to tell        
lies. When I told him this was wrong to tell lies,            
but he just laughed at me. The problem is, "Should I        
tell his parents or his teacher, or should I keep quietly?"
