Bob read Victor the Violinist to a group of third and fourth graders, then did something he does not always do on school visits: he brought the violin.
He played badly on purpose first. Then well. The point landed harder than any explanation would have.
The question every class eventually asks is whether Victor is real. Bob's answer has stayed the same: Victor is every child who wanted to quit but came back the next day anyway.
