Famous quotes containing the words types of, types and/or messages:
“... there are two types of happiness and I have chosen that of the murderers. For I am happy. There was a time when I thought I had reached the limit of distress. Beyond that limit, there is a sterile and magnificent happiness.”
—Albert Camus (1913–1960)
“If there is nothing new on the earth, still the traveler always has a resource in the skies. They are constantly turning a new page to view. The wind sets the types on this blue ground, and the inquiring may always read a new truth there.”
—Henry David Thoreau (1817–1862)
“Acknowledging separation feelings directly and sympathetically is the best way of coping with them. It is actually helpful to tell a toddler “I’ll miss you,” or “I will think of you during the day,” or “It is hard to say goodbye,” or “I can’t wait to see you at the end of the day.” These messages tell the child that he is important to the parent even when they are not together and that out of sight need not mean out of mind.”
—Alicia F. Lieberman (20th century)
