Russell and Elisa (Riverside Kids)

Russell and Elisa are growing up. Now that Elisa is bigger, she and Russell have more fun together. The only problem is Elisa's doll, Airmail. Elisa takes Airmail everywhere, and Russell thinks that's silly. But one day Elisa leaves Airmail in the library by mistake. And it's Russell who thinks of just the right thing to make his little sister feel better.
