Joined At the Hip

Joined at the hip are my sister and me,

If I tumbled off a ship I would grab her, and she would grab me.

Living on an island would not be so dreary,

For my twin sister would always be near me.

Sure I would miss the others of my family tree,

But at least I would not have lost the other half of me.

As one can see, we are never apart,

Because if we were, it would sure break my heart.
