In kindergarten I had a classmate that threw huge tantrums when she didn't get what she wanted. I remember one day in particular where she refused to eat the snack and drink her milk. Fine, so be hungry. But that wasn't enough, she screamed at the teacher to give her something else and then made a huge scene when the teacher tried to remove her from the classroom. I don't remember much about her after that. Can't recall if she kept coming to class or if she just shaped up in a hurry.
