What are you the sneaky family.
I think you should be more worried as to why your daughter has no respect for anything you say,
If my son was told not to take his ds to school, i can 100% guarantee he wouldn’t take it.
Reason being im his dad, and he does what his dad says, no questions no debates.
I presume your daughter knows the difference between right and wrong,yet still chose to disobey you,and went around it in a way that was very sneaky,
Having seen what your daughter was up too, you then choose to be just as sneaky, by sending her on a fake dog mission, just so you could act in a way that was equal to your daughters sneaky ness.
Your now going to have a child at school that may worry all day due to the fact she,s now DS less,or be concocting a pack of lies for you.
All because you didnt have words with her, when you seen it under her arm.
Imo you missed a perfect opportunity to re-enforce why your daughter should not take her DS to school but instead chose to be a thief.
I carnt see how that will get you any respect of your daughter,but maybe thats why she took it in the first place.
