Great story. I'm happy for her.
As for what Lome said, that's true, it's harder with children but at the same time it's slightly easier for women with children to find work and a place to stay if they're homeless. They have programs made especially for homeless women with children.
As for your sister, I'm sorry about that but she still has family, she still has you right?
This girl may have her fancy electronics but only because she knows she needs it to keep fighting. Smart woman, she used her brains and kept what she needed to get back on track. She had no one but herself. Her dad killed himself, her mother apparently was no help.
Being homeless is easier when you have friends and family to rely on until you can get back on your feet.
I remember when I was 7 and our house burned down, for the second time. Oh yeah, it happened. My parents spent a lot of money rebuilding it after the first fire and when the second happened they wouldn't give him insurance money because they thought he did in on purpose! <_<
If it wasn't for my grandparents and uncles taking us in, we would've been homeless too.
