Reject the HK trip offer

Well, today my boss asked me and the other colleague go to HK to visit their books exhibition. I guess the trip would be 3 days 2 nights. During this H1N1 period, booking air flights and hotel is very cheap, maybe discount 50%. Why he has to wait until this period then ask us to go there, because of saving cost? Doesn't care about employees safety. Well, this book exhibition I guess he just wants us to see and know how it looks like or maybe just let us to take a break over there.

So I rejected the trip offer, before this disease exists why he never asked us to go there. There's 50% for you to survive after coming back from HK. Nothing is more important than your own life. This disease is getting worst. And then I rejected by telling him a lie. Just told him that I need to attend my nephew's wedding. He nodded and said "Nevermine, next time then go".
