Famous quotes containing the words grey and/or gold:
“There is grey in your hair.
Young men no longer suddenly catch their breath
When you are passing;
But maybe some old gaffer mutters a blessing
Because it was your prayer
Recovered him upon the bed of death.”
—William Butler Yeats (1865–1939)
“The happiest two-job marriages I saw during my research were ones in which men and women shared the housework and parenting. What couples called good communication often meant that they were good at saying thanks to one another for small aspects of taking care of the family. Making it to the school play, helping a child read, cooking dinner in good spirit, remembering the grocery list,... these were silver and gold of the marital exchange.”
—Arlie Hochschild (20th century)
