For a moment, our narrator feels awkward. Then she sees a button Sarah wears. It says ';Rockhound' on it.';Do you collect rocks?' Sarah says she does! ';So do I,' says our narrator. And soon it's clear that these new friends are more alike than different. They scrapbook, draw cartoons, and even go hot-air ballooning.Lively verse and bright pictures celebrate this very close friendship.
