White Moments of Life
(The). The red-letter days or happy moments of life. The Romans used to mark unlucky days, in their calendars, with black chalk, and lucky ones with white chalk; hence Nortare diem lactea gemma or alba means to mark a day as a lucky one.
“These, my young friend, these are the white moments of
one's life.” —
