THE PAIN AND the Great One hardly agree on anything. But deep down, they know they can count on each other, especially at school, where it often takes two to figure things out. Like when that first baby tooth falls out on the school bus. Or when an unwanted visitor on Bring Your Pet to School Day needs to be caught. Or worst of all, when a scary bully says you're burnt toast. On days like these it can feel good not to go it alone.
