Posible theme of Chapter 34 of Walk Two Moons

One possible themes in Chapter 34 is that of perceptions. While waiting for the geyser to blow, everyone anticipates the experience in a different way. Most bystanders back away... Gram inserts herself into the experience... she revels in every moment, and Gramps is more enthralled by the sight of his wife's reaction than anything the geyser has to offer.
