I read that book as a parent of young kids. It made me realize I was doing FINE as a parent. A lot of us worry so much about every little thing. But if you put your kids first and do your best, you are a good parent. Even the worst parents ever (Glass Castle parents) raised a kid who wrote a great novel and seems pretty well-adjusted, considering. The scene when the kids were in the back of the (open!) moving truck, while the parents sat in the front, has always stuck with me as unbelievably shocking.
