I think that her comments to Joel were a bit out of order, but in fairness she had said to him very clearly, 'I don't want to discuss this tonight.' She'd lost her mate, she'd been drinking and she wasn't in a position to be able to look at the situation objectively, and she was sharp enough to recognise that and made it very clear that she would be willing to chat with him about it, but not right then.
After that, Joel just kept on and on at her. I felt like he forced her to speak to him. Once he'd done that, I don't think you can really blame her for going off like she did. Her comments may have been a bit unfair, but she had tried not to bring the subject up at that time. What would anyone else have done?
