Can’t Toss Them

There must be a psychological disease named for what I do, but I don’t know what it is. I cannot throw away cardboard boxes.

If I buy a new appliance or new equipment that comes in a box, I open the box to take out the item and then save the box and the styrofoam, in case I have to return it or move or need to repack it. I figure that it is better to put the item back in the packaging that it came in. It is safer that way and easy to deal with.

But friends are telling me that this is extreme and I should just throw out the boxes. But the though of throwing them away makes me very uncomfortable. Why would you throw away a perfectly good box?
