A resounding YES.
The sentence is a product of her irresponsibility. She wasn't able to fully carry out the court's instructions. She even has a legal team to remind her, which I have every reason to believe they did. How hard is it to follow concrete instructions written on paper or attend hearings on scheduled dates?
She cries because she doesn't believe that it is actually happening to her not because she realizes what she did was wrong. The thought of jail was only a fantasy of her detractors, but now she would play and live the part. The tears are for humiliation, frustration of her situation and anger with herself. She says she is sorry, but it was a little too late.
I don't feel hatred towards Lindsay Lohan. I'm not a big fan of hers either...especially now. I could've been until she kept doing silly things that created too much negative attention. It's funny that people all around her want to help her probably not all out of concern but because out of a good challenge. But even if you gather all Dr. Phils in rehabs, the change should initiate from within. And I believe Lindsay Lohan already had too many extensions on merciful judgment. She needs to be accountable. It may be the only way she could learn and change for good. Who knows, she might be having a beautiful comeback from the lowest of the low. She might have her own E True Hollywood stories.
