Roger that. If that had been my kid treated like that I would have been with her the next day and every day thereafter as long as it took to be sure she never got humiliated by some “adult” punk at that school again. They would not like me having lunch with my kid in that cafeteria.
My son once misplaced/lost/had stolen his 6th grade math book. When he asked the substitute teacher for help in obtaining a replacement, she told him he’d have to wait until the regular teacher (on extended medical leave due to a double mastectomy) returned. He damned sure didn’t wait that long. I wasn’t carrying a black flag or a knife, but they were lucky they couldn’t look into my soul at that point. I hate “adults” that bully children.
Had this been my child said food inspector would have found out what chicken nuggets taste like after they’ve been “recycled.”
