I’m just asking questions. I really don’t understand the sarcasm and hostility. A bit odd and definitely a surprise.
Sarcasm and hostility - me? Never!
You asked the question about how Leah's parents knew she got up after they left and followed her exact routine if they weren't there to witness that. I answered your question by pointing out that Leah was seen on CCTV at 8.15 which, even if they hadn't seen her, would suggest she was on her way to work as usual - surely this is logical?
However you replied by saying all it means she was seen then and there on CCTV. So I then replied to you by asking - where do you think she'd been then? What's wrong with that? It would be good to hear any new ideas on Leah's case and as no-one (as far as I know) has questioned whether Leah was at home that night I though it would be a good idea to get a new perspective.
If you have any new ideas or thoughts on where Leah might have been the night before then please let us know, it would be good to discuss.
