Every time I find something to go to the charity shop - or if I am not quite sure about getting rid of it - I put it in a box in the boot of my car. Then I wait a while to see if I miss any of these items. If I do, I retrieve the item from the car. If not, eventually I drop off the stuff at the charity shop. It's quite good because generally I don't miss any of it.
I was forced to do that with DH.
He was more ruthless than me in the past.
So ruthless, that it wouldnt be more than a day or two, and he would ask if the items were still about, and not thrown!
We worked out a system that they would be taken away where he wouldnt find them.
Left for two weeks.
If he hadnt claimed them back after that, permanently out they would go.
