I have a really hard time imagining a parent who goes to bed before her son is home the night before the first day of school, especially in a town with a curfew.
This is THE problem. The problem with Adam Lanza, the problem with my friend's soon-to-be-18 son, the problem with my bipolar cousin who is wrecking her life every time she goes off her meds. THE problem. It's a combination of a lack of effective medication/treatment and the lack of the ability to help these people live in a dignified environment that respects their autonomy as much as possible while also protecting themselves and others from their diseases.
I wonder, then, why he drove so far NW on 92 after the murders to that gas station, which was hardly the closest one?
FWIW, Cobb (gf's house) is not far, but it's not super close, either, 5-10m drive depending on where exactly she lives.
