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 "the common fate of all" mean in the
poem?

O what happens to everyone

O beloved by most people

O easily avoided

O unique to just a few people
