Right, what is junk to me is a treasure to somebody else. When I was cleaning at my mother's, there was a very old radio. My mother did not insist on keeping it because it is huge but I somehow didn't feel like throwing it out. I have already thrown out plenty of old clothes and the like but I somehow hesitated about the radio.
Later, when we had to move some furniture, I called two friends of mine to help. And one of them was really fascinated by the radio because it was pretty old and he was a hobbyist, so he kind of booked the radio in case I some day decide that I am not keeping it.
And this is not the only example I can think of!
