Enrollment fee of a cram school = 22,000 yen ($215.69 €160.58)

My son entered a cram school this month. Its enrollment fee was 22,000 yen ($215.69 €160.58). At the first time lesson, my son skipped the lesson. He escaped to another place, because he did not want to go the cram school. The principal of the school called us three times and told us my son did not show up. His sister and his mother searched him. But they could not find them. After 15 minutes later, he came back. His mother forced him to call the school to apologize this incident. My son promised with the principal to go to the school next time. Fortunately he attended to the second lesson.
