There was one time during sec 4 O'Levels year, me and my friends
felt stressed up about school and we decide to pontan (skip
school)
While we are on the way out of the school gate, my math teacher
came in by her car and she saw us. She looked at us and shook her
head. Our natural reaction was to run away.
The next day, while having math class, she made the whole class
stand because non of us were able to solve the math equation. She
then said "Whoever managed to solve this problem can have a
seat".
I raised my hand up high to volunteer.
Being a rebel in school, nobody was expecting me to solve the
math and they thought i must be playing a prank on the teacher. But
little did they know something... 
I walked up to the board, grab the chalk, and solved the math. I
went back to my table and sat down confidently because I knew the
answer was already 100% correct.
Little did they whole class knew we skipped school and went to a
nearby Mcdonald outlet and practise our 10 years series and I
happened to solve that very same math question! 
smlj.. when i pontan during my sec sch.. how to walk out of
gate? I just climb the fence(abt 2 metre high) and jump down then
sprain my ankle. Then i can go see doctor liao get mc rest at
home.
