There are some happy, easy natures to whom jealousy is, through life, unknown.

They are to be envied.

Jealousy in a grown-up human being is bad; in a child it is terrible.

Had you told Mrs.
Cole--good mother though she was--that her daughter Mary, aged seven, suffered tortures through jealousy, she would have assured you that it was not, in reality, jealousy, but rather indigestion, and that a little medicine would put it right.
Mary was quite helpless.

What is a child to do if she is jealous?
Other children do not understand her, her elders laugh at her.
