- Read the following poem and answer the questions that follow. I AM TIRED OF TALKING IN METAPHORS.............(Solved)
Read the following poem and answer the questions that follow.
I AM TIRED OF TALKING IN METAPHORS
I will talk plainly
Because I am moved to abandon riddles
I will tell you of how
We held our heads in our hands
Because the owl hooted all night
And the dogs howled as if mourning
We awaited the bad news
We received it:
Our mother blinded in one eye
Crippled in the right leg
Because she did not vote
For her husband’s candidate
I will remind you
Of when the peeled plantains
Stood upright in the cooking pot:
We slaughtered a cock,
Anticipating an important visitor
We got her:
Our daughter – pieces of flesh in a sack
Our present from her husband.
No! I will not use metaphors
I will just talk to you:
I do not fight to take your place
Or to constantly wave my fist in your face
I refuse to argue about
Your “manly pact”
With my father
You’re buying me for a bag of potatoes
And pepper
All I want
Is for you to stop denying me
My presence needs no metaphors
I am here
Just as you are
I am not a machine
To dismantle whenever you whim
I demand my human dignity
Questions
(a) Who is the persona in this poem?
b)What is the message of this poem?
c) Explain the speaker’s attitude towards the subject matter
d)Give one character trait of the speaker.
e)Discuss two elements of tradition highlighted in the poem.
f)Identify two poetic features of style used in the poem.
g) I am not a machine. (Rewrite adding a question tag.)
