As far as goals go, the LCs can only work on so much, otherwise they'd all be like Allison or even worse, live there permanantly.Kelly wanted to work on her goals and go home. She didn't want to deal with the people in the house or try to fix every single thing in her life.
I think Kelly deserves to graduate. I don't think she's changed drastically, if at all. I do, however, think that she's gotten all she's gonna get from the SO house. Going by Kelly's personality alone and not comparing her to others, I think they've done what they can with her. There may not be huge improvment but maybe Kelly's personality is handled better by praising her for small improvments. I never expected a dramatic change in her.
It's kind of like high school. Some people graduate with high honors, others just get by. I don't think that she has failed in any way butI don't think they should invest anymore time in her either.
Therefore, a passing grade. Not well deserved but not undeserved either.
...My opinion.
