You know Prudy has all sorts of whims.

Don't you know how she has wanted us to call her Jessie sometimes ?" "Why, no, indeed, grandma, she isn't lame," said Susy, laughing.
"Sometimes she will run about the room as well as I do, and then, in a few minutes, when she thinks of it, she will limp and take hold of chairs.

Mother, isn't it just the same as a wrong story for Prudy to act that way?
If I did so, you'd punish me; now, wouldn't you ?" "I don't know what to think about it," said Mrs.Parlin, gravely.
"Sometimes I am afraid Prudy is really becoming naughty and deceitful.

I thought once it was only her funny way of playing; but she is getting old enough now to know the difference between truth and falsehood." There was an anxious look on Mrs.Parlin's face.
