Famous quotes containing the word exception:
“Lets face it. With the singular exception of breast-feeding, there is nothing about infant care that a mother is innately better qualified to do than a father. Yet we continue to unconsciously perpetuate the myth that men just dont have what it takes to be true partners in the process.”
—Michael K. Meyerhoff (20th century)
“For a parent, its hard to recognize the significance of your work when youre immersed in the mundane details. Few of us, as we run the bath water or spread the peanut butter on the bread, proclaim proudly, Im making my contribution to the future of the planet. But with the exception of global hunger, few jobs in the world of paychecks and promotions compare in significance to the job of parent.”
—Joyce Maynard (20th century)
“There are those who would build the Temple,
And those who prefer that the Temple should not be built.
In the days of Nehemiah the Prophet
There was no exception to the general rule.”
—T.S. (Thomas Stearns)
