Shadowland question

I read this a long time ago, so I don't remember how the ghosts know about Suze in the first place. They might know she was just ignoring them.
But even if she could, she's not the kind of person to do that. She's the only one that can see them and she'd feel guilty leaving them on their own. Since, sure they're ghosts, but essentially, people who need help.
Besides, I doubt she'd be such a great actress. It'd be hard for anyone to act normal with a ghost right there.....

acting like their not there would be pretty hard, cuz noone else can see her/him/them. i think that they can just tell that Suze is able to see them so thats why the ghosts try and get her attention.
