Notice from Daniel for KOGM 2006

I must be a luck one because I have a lazy sister. I used my sister's home address for the KOGM 2006 Competition but I never told her that there will be a letter for me from Daniel. Since most people received their letters on last Friday, Saturday or even Monday, I expected mine was sitting in her mailbox since that time. Because of my sister's laziness, she checked her mailbox until Wednesday, the first day I am in HK. Here is the problem, the letter is addressed to "B-024" rather than my name (Jim Chan), if my sister checked her mailbox before Wednesday, she would have thrown away (or returned) this letter without thinking that it's my letter. It's a close call, is it not?
