I'm a librarian who loves anime, manga, and reading a wide variety of genres.
The mom (Jean, I think) to her kids, Molly and Michael:
"I tried to talk to Dave about [Heather] before you all came home, but he said I wasn't trying. He said I didn't love her enough."
Okay, why did Jean and Dave get married? Not only is Dave doing nothing to help his obviously troubled 7-year-old daughter ("shrinks mess up your head" or something), he's a terrible husband as well.
