Do You Know Why I Can't Sleep?

Now,it's eleven.Night.
Why can't i sleep?!
A few moments before this,i was sleeping soundly in my bed.
Sweet dreams,although i couldn't remember much of it.
And suddenly my handphone rang.
It's her, my classmate again(let her remain anonymous).
I was so angry of it.Worst of all,she called the second time.
She likes to call me when she has problems,with no concern for me.
I am the victim.I was angry.
So now i'm sitting here,fuming.
She could just ask me anything,any silly,boring or important questions at school.
But she didn't.She prefers to waste her money and my time.My energy.
11.14p.m.Sh**.
