Mma Ramotswe starts her day:
She sipped her tea and made her way to the back of the house. There was nothing to see there, just a couple of empty barrels that Mr. J.L.B. Matekoni had brought back from the garage for some yet-to-be-explained purpose. He was given to clutter, and the barrels would be tolerated only for a few weeks before Mma Ramotswe would quietly arrange for their departure. ...I just picked up The Good Husband of Zebra Drive, by Alexander McCall Smith, and was surprised to find that it started with a decluttering story!
It was the same with his trousers. Mma Ramotswe kept a general watch on the generously cut khaki trousers that her husband wore underneath his work overalls, and eventually, when the trouser legs became scuffed at the bottom, she would discreetly remove them from the washing machine after a final wash and pass them on to the woman at the Anglican Cathedral who would find a good home for them.
But in the real world, under normal circumstances, I would advise you to not get rid of someone else's things without his or her approval.
