If I had a 5 day suspension for every question I skipped on tests like that, fuck I would've been out of school more than in it. Gotta love the American education system.
In all seriousness though, I think yeah, the parents are overdramatizing this, and the kid also. On the other hand, 5 days for not listening? Even if they can justify the suspension, 5 DAYS WTF!!! I've gotten less for a helluva lot more than just not listening to the teacher.
The fact that the higher ups think this is perfectly acceptable....fuck even if I ever move to the states, which I won't, but if I did, I would make sure to move back before having schoolage kids, no fucking way that school system is safe for kids. That much weight on standardized tests at that age....sickening.
Jam it back in, in the dark.
