Artist, Writer, Poet

You call me an artist,
But I say no.
I can't draw or invent,
But I can imagine and write.

You call me a writer,
But I say no.
I can rewrite stories or tell them,
But I can never write a story with an ending.

You call me a poet,
And I say yes.
I count rhyme or count syllables,
But I can write free-verse in no time at all.
