You never had found and you did not understand quiet.
Did you ever see a wise mother come into a noisy nursery where perhaps her own children were playing excitedly with several little companions, who had been invited in to spend a rainy afternoon?
The mother sees all the children in a great state of excitement over their play, and two or three of them disagreeing over some foolish little matter, with their brains in such a state that the nursery is thick with infantile human dust.

What does the wise mother do?
Add dust of her own by scolding and fretting and fuming over the noise that the children are making?
No--no indeed.

She first gets all the children's attention in any happy way she can, one or two at a time, and then when she has their individual attention to a small degree, she gets their united attention by inviting their interest in being so quiet that they "can hear a pin drop." The children get keenly interested in listening.

The first time they do not hear the pin drop because Johnnie or Mollie moved a little.
Mother talks with interest of what a very delightful thing it is to be for a little while so quiet that we can hear a pin drop.

The second time something interferes, and the third time the children have become so well focused on listening that the little delicate sound is heard distinctly, and they beg mother to try and see if they cannot hear it again.
