What many insist is amazing or awesome in their humdrum lives is usually nothing more than average or commonplace. Next time, try "affect" when the lazy urge to use "impact" strikes. The superintendent's presence would tend to "affect" the teacher's classroom environment. See how that works? Keep it simple, silly.
Why a principal would live in fear of reprisal for doing his or her job properly is ridiculous, or it's just more small-town political paranoia. The school board shouldn't have to hear about this behavior from meddling parents. Why is the superintendent there in the first place where she clearly doesn't belong? Once again, it's simple.
It's encouraging to learn that first-graders aren't allowed to have cell phones in class, though it's disappointing children that young are involved (but not impacted). So, does being observant stop at noticing her car in the parking lot or taking the extra step of escorting the little ones inside to get a closer look?
