Famous quotes containing the words sweat and/or test:
“When my face turned toward his,
I averted it
and looked at my feet.
When my ears clamored
to hear his talk,
I stopped them.
When my cheeks broke out
in sweat and goosebumps,
I covered them with my hands.
But Friends,
when the seams of my bodice
burst in a hundred places,
what could I do?”
—Amaru (c. seventh century A.D.)
“Wild roses, at your back porch, break their blood,
And bud to test surprises of sea air,”
—Howard Moss (b. 1922)
