Playwright Wendy Wasserstein's Younger Mother

I love this passage from Wendy and the Lost Boys: The Uncommon Life of Wendy Wasserstein by Julie Salamon (Penguin Press, 2011):

"At family functions Morris [Wasserstein's father] quietly approached Lola's relatives and asked them, 'Do you know how old Lola [Wasserstein's mother] is?' He never got a definitive answer, because no one knew for sure. Lola enjoyed the game. At Georgette's sixtieth-birthday party, Lola asked a guest, 'How can my daughter be sixty when I'm only thirty-eight?'"
