Absolutely hilarious the people defending Luann. There is literally nothing in this situation that she has done correctly, starting with the archery. You might be mad at the mom but who cares when a complete stranger shows up with a bow and arrow (timing being everything with the Norway attack) and shows off for the students.
So suddenly it’s all good to ignore actual rules and safety of the students because it’s Luann? Gee golly, if she only asked permission first.
Knowing the writers this will pass on and no real consequences.
I’ve said this a million time, who’d hire her to drive students after being fired from watching them.
