I had left the kids' halloween sweets in their buckets in a cupboard.
ds (10) has complained for the last week that his were going missing.
Initially, I dimissed this but then ds found a bag with empty sweet wrappers behind a cushion in the play room. There was also a wrapper from a snack only dd (9) eats.
I confronted them both and said I wanted to know who had eaten the sweets. Ds points out that it can't be him because (a) they were his and he would hardly have complained if he had eaten them and (b) there were wrappers there from things he does not eat.
Dd insists that it was not her. She would never do something like that - either take the sweets without asking or steal from her brother. She would never lie to me. If I truely love her, how can I not trust her. In the same position she would trust me as she loves me. This was all very empassioned with tears streaming down her face.
Then ds is inspired and says he can use his fingerprint kit to prove it was not dd. She goes nuts claiming that she will not submit to this as it shows we do not love or trust her. When I say it sounds like a good idea and would vindicate her, she finally says she had forgotten she had eaten them.
This all sounds trivial I know, but you had to hear the performance to believe it. I am also concerned that it forms part of a pattern of hehavious and she lies a lot about small things (just to make herself look better).
AIBU to think this is beyond normal childish deceit? If so, what, if anything should I do?
