0Roger and Adelia are the very best of friends. They've spent many springtimes collecting birds' nests, autumns jumping into piles of colorful leaves, and winters building snowmen. When the time comes for Adelia to move away, the two friends must say good-bye. But Adelia has one parting gift for Roger: She will teach him, once and for all, how to climb a tree. Lyrical and colorful, the narrative flips between Adelia's instructions ("hold on tight," "move up when you're ready") and her packing list (things they loved to play with, things they were supposed to throw away). By the time the moving van pulls up, Roger is ready to start his climb. But now, he's afraid of "letting go." In a sweet reveal, we learn that Adelia has left behind a soft landing, making sure that--for Roger--falling is the easiest part.
