Carl Sandburg - Gypsy

I asked a gypsy pal
To imitate an old image
And speak old wisdom.
She drew in her chin,
Made her neck and head
The top piece of a Nile obelisk
and said:
Snatch off the gag from thy mouth, child,
And be free to keep silence.
Tell no man anything for no man listens,
Yet hold thy lips ready to speak.

Carl Sandburg
