Cassie’s mom is taking her daughter’s attempted elopement well. No grounding, no empty room, no nothing. Plus she’s giving Cassie cookies! Come on, woman! She blatantly defied your orders while you were on vacation!
If Mimi really wanted to teach Cassie a lesson, make her an equipment manager. Have her do suicides (or the softball equivalent of suicides) until she pukes. Put her on the bench for the season. Have the pitching staff tee of on her. I’d take anything over just giving her the silent treatment during practice.
Besides, the shunning of Cassie could be justified if Milford got spanked by Tilden, but they didn’t. How does the person responsible for losing the game not get shunned along with the person who abandoned her team?
