Read the last stanza from "The Rainy Day" by Henry Wadsworth Longfellow.
Be still, sad heart! and cease repining;
Behind the clouds is the sun still shining;
Thy fate is the common fate of all,
Into each life some rain must fall,
Some days must be dark and dreary.
What does the phrase "cease repining" mean in the stanza?
A stop being upset
B accept sorrow
C open wide
D learn to change
