“He laughs. And in his laugh I hear bliss. I hear feet dancing, the rush of skirts twirling. The sound of children.

Laughs longest.”

“Can I take advantage of you in the limo?” His eyes laughed at me. “By all means, angel mine.”

“it is always a genial laughter. Not at mere weakness, at misery or poverty; never. No man who can laugh, what we call laughing, will laugh at these things. It is some poor character only desiring to laugh, and have the credit of wit, that does so. Laughter means sympathy.”
