Money going missing from my purse for weeks. Couldn't fathom it. Finally made a general announcement. Heartfelt denials from DP, DS, DD. It stopped for a few days then started again. Tonight 60 quid taken, only DD could have done it. I grimly started searching her room inch by inch, she denied it, carried on searching for an hour - every pocket, every book, every ornament etc. She carried on denying. Got tired of it and just said to her that I was going to find the money if it took all night, I was prepared to search the whole house. 60 quid suddenly appeared in the kitchen, she 'found' it and marched up to me quite aggressively saying I must have left it there. I told (quite calmly) that I believed she was lying and had put it there herself, and carried on searching. Another half hour later she went into her brothers bedroom and came out with another 70 quid.
I can sort of understand how she got into this whole scenario, I can sort of understand that it is probably to do with starting secondary school etc, I can sort of understand that she is only 11 and didn't think it through.
What I don't understand and this is really worrying me is that she could lie so plausibly over such a long period, that she could be so calculatedly sneaky and that she appears to feel no guilt. She is upset that she's been caught, but I see no sign whatsoever that she is actually feeling bad about the betrayal of trust. I now feel like I don't know this child, and I certainly don't trust her. I didn't take action for a long time because she was so convincing, I thought I might be going a bit dotty myself and spending it without remembering.
All pocket money, savings box, Ipod etc. have been taken away. I have cancelled a trip to town with a friend scheduled for this weekend. Any thoughts on what I should do to try and map a way forward for both of us?
