i understood why dale felt so angry and betrayed , both by his sister 's decision to stay and live in maine with her mother-dale made it clear he 'd never talk to chrissy again if that 's what she chose , and i think he meant it-and now her decision to come sponge off the man who had raised her , a man she 'd called `` dad , '' most of her life , until the truth was revealed-a man she had ultimately rejected .
