What was Laurie Saunder’s parent’s reaction to The Wave?

Mrs. Saunders finds the experiment off-putting. She thinks it sounds too militaristic, and it seems like an odd way to teach history. “We’ve raised you to be an individual” (50), she says. However, Laurie is enthusiastic about The Wave. She thinks the class can benefit from some team spirit, and she points out that no one has picked on Robert since the experiment started.
