I suddenly remembered.

Today, KimPong ran out of class for early recess. I ran out toos.

Xuewei wanted KimPong to get caught, so she shouted:
WA! Kimpong! You want go early recess is it?

KimPong was pointing middle finger at her? Den i told him:
Eh, KimPong, next time you want early recess, jump down can alr. Very fast one.

Xuewei was laughing like hell. Den KimPong pointed middle finger at me.

Den i added: But i think you cannot jump lahs, cause you will bounce up.
KimPong: You shut up la, you so cb.
Me: wait, i havent finish. You will bounce back up, den go down again den up & down, up & down. Den by the time you stop bouncing, recess over alr.
