The Stick-Together Families by Edgar Guest.

Part 2 of 3.

There are some who seem to fancy that for gladness they must roam,
That for smiles that are the brightest they must wander far from home.
That the strange friend is the true friend, and they travel far astray
they waste their lives in striving for a joy that's far away,
But the gladdest sort of people, when the busy day is done,
Are the brothers and the sisters who together share their fun.
