Read the poem and answer the question below

I lost my talk

The talk you took away.

When I was a little girl

At Shubenacadie school.

You snatched it away:

I speak like you

I think like you

I create like you

The scrambled ballad, about my word.

Two ways I talk

Both ways I say,

Your way is more powerful.

 So gently I offer my hand and ask,

Let me find my talk

So I can teach you about me
