Why mood swings?

I hate it when it happens. I was still very n2 about today's b'day celebration, plus the fact that so many exciting things happened during the whole process. But 30mins before the celebration, i jus lose all my n2'ness. No mood for anything.

Im sry to wr and qw for showing such attitude on you 2's bday celebration.

Went for cca later and tried to relax myself. Hope i dun bring such negative attitude tml class outing.

睡了会更好。
