Laugh and the World Laughs With You...

Allison, through her tears, after spinning around, falling on the grass, crying, and getting soothed by Mommy:

Allison: When you cry, does the whole world cry?

Mommy: No. In fact, there's a famous expression: Laugh, and the world laughs with you; cry, and you cry alone.

Allison, giggling: That's funny, Mommy.
