I'm always weirded out that no one ever seems to do anything. Like no teachers, staff, etc. ever try and help them.
Do they all just live in shitholes? I don't doubt it.
Also, you gotta admit that they're almost comically evil in this. Like they just unprovoked walk up to her and spray milk in her hair for no reason when IN THAT EXACT SAME MOMENT she's just thinking "Oh I wonder if tomorrow I'll set with the others and make friends."
You could make the argument it's so over-the-top it's funny.
