Life is the same every day for Ben, and that's just how he likes it.

Ben likes things the same way every day at school--he sits at the same table, eats the same lunch, and likes the daily class routine. But when his teacher leaves to have her baby and a substitute teacher comes and changes everything, Ben gets upset. He liked everything the way it was before! But soon Ben starts to think differently about change and realizes that doing things another way can be fun.
