Dear Peter,                                              
     Thanks very much on inviting me to your birthday  
party on Sunday. I'd like very much come but         
I would have an examination on Monday morning. It is  
a very important exam but I can't afford to           
fail it. I'll spend all the whole weekend reading     
and prepare for it. So I'm really sorry that          
you won't be able to come this time. Hope you         
can understand. I'll take this chances to wish         
you wonderful time on your birthday. Happy            
birthday, Peter, and many happy return of the day!                                               
                                                                 Li Ming
