Sure, they squabble at times. You'd think with this many toys in the house there would be nothing to fight over. Not so, my friends, not so.
Generally, though, they are already each other's best friend, and that's the way I like it. Elizabeth refers to her sister as "my friend Lilli", just as often as she calls her "my sister". And nothing makes Lilli happier than hugs from her sissah.
If you didn't have a sister, who would share the joy of a swing on a spring day with you?
Who would, and I shudder to even say this, share their lollipop with you?
