Read "We Wear the Mask," by Paul Laurence Dunbar, then answer the question that follows. "We Wear the Mask" by Paul Laurence Dunbar

We wear the mask that grins and lies,

It hides our cheeks and shades our eyes,—

This debt we pay to human guile;

With torn and bleeding hearts we smile,

And mouth with myriad subtleties.

Why should the world be over-wise,

In counting all our tears and sighs?

Nay, let them only see us, while

We wear the mask.

We smile, but, O great Christ, our cries

To thee from tortured souls arise.

We sing, but oh the clay is vile

Beneath our feet, and long the mile;

But let the world dream otherwise,

We wear the mask!

Explain why Dunbar would choose to use a symbol of a bleeding heart in his poem instead of using literal language to explain how he feels.
