She’s unreal isn’t she ?? like a major show , imagine your friends or sister going on like that? I have swapped and changed my opinion on the Mam and yes she is an enabler but maybe she is the only constant thing the kids have in their life, their Ma’s a junkie like for real and sells her hole for drugs , Lisa probably hates her but has to put up with her as and when she decides to throw a few crumbs her kids way. Who is she living her life for though ? Like really ?
