Never underestimate how upset people can get when a kid does longhand addition the old way (write numbers under each other, carry the ones) rather than some more "holistic" way.

I'm not sure why the commenter is being downvoted. I too can make a drama, literally capitalizing one of the worst words ever invented, "actually," about a vague antagonist, and rile people up, letting their imaginations fill in whatever boogieman they feel wronged them in school. What specifically is the situation? I don't want to speculate.
