How do the curses in her life become blessings?

As Walls said, "Every situation is filled with both blessings and curses, and it's entirely up to us which ones we choose to focus on." The family is dysfunctional yes, but they stay together and make the best of it. Jeanette's parents drag their children around the country not because they can't make a living, but because they simply refuse to. But there are the good things, the hope, the bond between the children; the stars Rex give the kids for Christmas when he has nothing else to give.
