<human>: Can you provide a brief rundown of the text in within 3 sentences?

So I just created this account for anonymous purposes. I need answers from strangers. Girl went to her friend's birthday party at some sportsbar with her son. I was just getting home myself as she was unloading the car. She was moving suspiciously fast. After she laid the kid down I could tell how drunk she was by her obvious lack of balance and she was speaking in drunkanese. I thought it was pretty bad and told her she was an idiot for what she did. She blew it off saying "well if I would have been pulled over it would have been a problem, but I didn't, so there is no problem." THEN, I hear coughing coming out of the bathroom. Realizing she must be in purge phase I go in and sure enough, she's got her face in the sink spewing chunks. She passed out soon after. So, what am I supposed to do with someone with blatant disregard for her own life, her innocent 2yo son's life, and any innocent motorist/cyclist/pedestrian's lives she may have ended?
<bot>: Girlfriend drives home drunk with 2yo in the car, to the point that she can barely walk or talk, and ends her night with a barf session. What do you do?
