Younger brother changes his mind.

My younger brother changes his mind and telephone me in the morning at about 9.05am to tell me that he had recovered from diarrhoea and is able to attend this evening reunion dinner after all.
When I hear that my heart sank. Not because I don't wish him to attend but I feels a bit pissed off because he had told me last Sunday that he is unable to attend but now changes his mind.

Anyway I told him to get ready and wait for me below his flat at 5pm for me to pick him up.
I am a bit reluctant but have no choice. I think he was looking forward to the "Hong Bao" that we might give to him and the sumptuous buffet dinner that he seldom have the chance to eat.
