Late for school

I woke up this morning,
And looked at my clock,
I am so dead,
It's nine o'clock!

I shove on my clothes,
And run down the stairs,
I gulp down my breakfast,
With no other cares.

I run to the bathroom,
To brush my teeth,
But unfortunately,
in the bathroom is my brother Kieth.

My mum comes over to me,
You silly girl Faye,
You must have your days mixed up
It's Saturday!
