Famous quotes containing the words register and/or definitions:
“Never to walk from the stations lamps and laurels
Carrying my fathers lean old leather case
Crumbling like the register at the hotel....”
—Philip Larkin (19221986)
“The loosening, for some people, of rigid role definitions for men and women has shown that dads can be great at calming babiesif they take the time and make the effort to learn how. Its that time and effort that not only teaches the dad how to calm the babies, but also turns him into a parent, just as the time and effort the mother puts into the babies turns her into a parent.”
—Pamela Patrick Novotny (20th century)
