Frown of the clown, upside down.

Solitude-

"Laugh, and the world laughs with you;
Weep, and you weep alone.
For the sad old earth must borrow it's mirth,
But has trouble enough of its own.
Sing, and the hills will answer;
Sigh, it is lost on the air.
The echoes bound to a joyful sound,
But shrink from voicing care."
