Laugh and the world laughs with you,
Weep and you weep alone;
For the sad old earth must borrow its mirth,
But has trouble enough of its own.

Ella Wheeler Wilcox (1850-1919) American author, poet, temperance advocate, spiritualist

Poem (1883-02-25), “Solitude,” ll. 1-4, New York Sun

Possibly the most famous of Wilcox' works, these are the first four lines (the only ones anyone remembers) of three eight-line stanzas. Wilcox was paid $5 by the Sun.

Wilcox' original title was "The Way of the World," but the Sun editor changed it to "Solitude." She kept that new title when it was collected into Poems of Passion (1883).
