In the book trumpet of swan What unwise thing did applegate do?

In the book "Trumpet of the Swan" by E.B. White, Applegate, the father of Sam Beaver, made an unwise decision to take Sam away from his family and bring him to a remote island in order to protect him from the ridicule of other humans due to his inability to speak. By isolating Sam, Applegate unintentionally deprived him of important social interactions and learning opportunities, hindering his emotional and developmental growth.
