Yeah, I was cringing when poor Josh said he doesn't have it in him to be the son she wants him to be or to make her proud. Lauri just sat there. Why not at least tell the poor kid he makes you proud now and that you love him no matter what? I'm sure there's something about him that would make a mother proud. She's not very encouraging. She just sat there silent, reinforcing his belief that he's useless in her eyes. Then at the end she told him she knows he has it in him to be the son she wants him to be. In other words, "you are currently worthless, but I have faith that you can be good enough for me if you really try."
