Sarah's timidity yielded to Gypsy's stronger will.

If Gypsy took a fancy to climb a ruined windmill, Sarah would scream all the way, but follow.

If Gypsy wanted to run at full speed down a dangerous steep hill, where there were walls to be leaped, and loose, rolling stones to be dodged, Sarah scolded a little, but went.
A girl more selfish than Gypsy would have been ruined by this sort of companionship.

Her frank, impulsive generosity saved her from becoming tyrannical or dictatorial.

The worst of it was, that she was forced to form such a habit of always taking the lead.
She lay awake some time that night after Sarah had fallen asleep, listening to the strange whispers of the wind in the trees, and making plans for to-morrow, until at last her happy thoughts faded into happy dreams.
She did not know how long she had been asleep, when something suddenly woke her.
