I Am Not

I'm not a whiteboard,
I'm not yours to erase.

I'm not a story,
I'm not yours to create.

I'm not a pebble,
I won't be tossed and turned.

I'm not a pet,
I won't do as I'm told.

I'm a secret,
So please keep me safe.

I'm a lock,
And I'm giving you my key.

I'm the sea,
And I'm letting you in.

I'm a flower,
But don't rip me apart.
