one thing about them being good parents when sober and on their meds. It's almost worse because of the lack of consistency. I would argue that from a child's perspective it's actually cruel for a parent to be inconsistent, on purpose or not.
When she's a good parent it's, "see what it could be?" And then it is ripped away and replaced by drunk mom. It's so, so, so ****** up. And so unfair to the children.
