Wow, that woman with the son is both a shitty mom AND a shitty person! Good to know. She can't teach her own kid self-control and then she's badmouthing the only reason she still has a kid AND not probably saddled with a fuckton of debt for burning down a library.
As other commenters said, her parents are also incredibly shitty. I do hope they won't suddenly come out of the woodwork with a sob story of how ~they're just normal people, they can't cope with having a 'different' child~ but now want to reconnect and have her help them with their problems after she became famous or something.
