Okay this is my thing about this story. This is where effective parenting comes into play. My mother taught me EARLY in school days, if I REALLY gotta go, GO, and if there is any reprocussions, then let her know and she'll handle it. My mother was not only a teacher, but very active in my education. I was to follow rules, but as far as this is concerned, screw the teacher, if you gotta go you gotta go. Of course theres always my 50% rule of "we dont know the full background" of the story too.
