Montessori Quote
A child has learned not only to keep silent, but when he should be silent. He has not only learned the various kinds of greetings, but he has also learned which one to use with another child, with his mother or father, with a stranger, or with one who is old and respected. In other words, he must use according to time and circumstances the many things which he has learned perfectly.
Maria Montessori, The Discovery of the Child, p. 95
