Pencil

I am the pencil I write with,
broken and cracked,
barely held together. 
At first glance, you would think it normal
you pick it up, thinking you'll make it yours.
Yet when you look closer, you see the damage.
So you throw it back down, 
And find a newer one.
I am broken.
I am cracked.
But please don't throw me down again, 
you maybe the one to break me permanently.
