Only my items in the full house grow legs and take themselves off on an adventure with no assistance from anyone else in the household 
Running late on the school run, took my necklace off as it was annoying me, left it on the counter. (Which I never do because of this reason- my mistake)
Went to put it away that night and its gone.
No one has seen it, no one has moved it.
It grew legs and took itself on an adventure- who knows when it may return.
Dh and the 2 dc can leave items anywhere in the house and I do not touch them. If they have made a mess i will point it out and ask them to deal with it but I will not touch it as it's not mine to rearrange.
I very rarely leave stuff lying around because of this. Lesson learned again.
Anyone else have this issue in their house or just me?
