My dad's been exceptionally worried about my sis's O Levels.
He's forever asking my sis to study. Whatever else she does, she has to go back to studying. I've never seen him so worried about me before, not even when I was taking my A Levels and I had really horrible prelim results.

I was in the toilet last night when I heard him talk to me sis, trying to get her to focus on studying. She was looking at her Michael Jackson CDs.

Dad: Eh so exam on MJ is it?
Sis: Take a break what. Aiya, I'm studying la.
Dad: So tomorrow's exam will ask you about gravitational pull of the moonwalk la.

HAHAHAHAHA.
I don't know where that came from. My dad's never this funny.
