Go school is wasting time?

ya... a question
go school is wasting time? isn't?
for today...i feel so...
before the recess
it can say that totally is free period...
first period - miss Ooi class...
she didn't teach anything just give some work for us to do
second n thrid period - pn Tan class
she absent today
fourth n fifth period - pn Khoo class
it was same also absent today
recently, teacher always absent
it was a part of the reasons
why i skipped school
when the teacher suddenly absent
it's no idea for me
what i can do for this free period...
erm... studying... it's too noisy n no book also
erm... sleeping... the school are no allow student sleep in the class
so... i just can chat with someone it was wasting my time...
after the recess
the last three period - miss khoo class
carry out the experiment
but have a small accident happening
Ah Pig hand was burnt
she put her hand on the top of bunsen burner
sadly... careless Pig Pig...
