this explains why.

This is why I did not go to school today:

Ok, my mum had to wake up early to go to this course. And around 6, she said she's leaving and she said "don't forget to go to school" And so, I catch up on my sleep again because I often wake up at 6.15--So, there's still 15 minutes of sleep. Why waste?

But that 15 minutes turns to 3 hours. And when I woke up it was 9.15! I was terrified. I hope mum does not finds out and I hope my brother did not take his leave today.

GEEZ!

until then,
