Thanks.
Yeah, I'm trying to figure out what to make of the parents. If GP's parents texted each of them once or twice, asking about the kids, I can see the Laundries not answering. They could think "yeah, your daughter dumped my son and I don't want to hear from you" or "talk to your daughter yourself! She knows where Brian is. She knows he comes home when he's...!" or some such thing. It seems they got the attorney after the police had knocked on their door. Did they think their son was being unjustly accused of something? Or do they think he did it? I guess that's the million dollar question.
BUT I feel that knowing more about what GP's parents said in their texts to them, and how many texts they sent, would give us a better idea of just what the Laundries were ignoring.
