I think she lived with friends, someone else with more knowledge might be able to expand on that. There does seem to be very little information about her post school pre call handler life. Of course it’s always possible she lied and she did live with her parents and do a series of minimum wage jobs. I've known a few situations like that where the parents have hoped the child will go back into education or get a non dead end job and the child has just coasted along. If the truth is she didn’t move out but just had a vey uneventful life subsidised by her parents until she was earning enough in her call handler job to rent her own flat then it’s not surprising she doesn’t talk about it. I mooched off my parents until my dad pulled strings and got me a well paid job doesn’t fit well with her poor victim status.I didn't realise she left school at 16, that makes so much sense now regarding her poor writing skills. She just stopped and never progressed. No wonder she uses words she doesn't understand. She is still the toddler that's trying to talk like a grown up.
Where did she live at 16? Was it with Slumdad and did he or another family member own the chippy?
