I mean the crazy lady was the reason she missed her train ofc she can get mad and ofc its plot
I mean, the old lady argued with her first so it's normal that she'll argue back
I guess it's a question of personality. I wouldn't have argued with her. One, I'm patient and I don't mind waiting for the next train too much. I'd get annoyed if it's when I'm going to work, but even then I'd only be annoyed for a bit. Second, I wouldn't argue with a crazy woman, because... what's the point? That's just waisting your breath and instead of letting out some steam, it'll only make you angrier, because it's obvious how unreasonable the crazy lady was. I would've gotten away from her. Third, here where I live, you gotta get away from the crazies. You never know what they might do. And sure enough lol
So... I read the first chapter and I'm like: why argue with a crazy woman just because you missed your train. Yeah, you'll be late but come one. Tsk tsk tsk
