Learning to draw [with a twist]

I am fourteen,
And my best friend is teaching me to draw

She says im getting better
But sometimes get to close to the line

She says always draw inside the lines she calls veins

She teaching me to draw,
She says are time is almost over though
So with tears in our eyes
We say goodbye
And draw our last picture
And straight through the vein I draw her name

Her name is razor
