I usually only get rid of old clothing/shoes of Shep's. He can have something in the closet for 2yrs, never wear it but still want to keep it. There are individuals who can use that clothing. When it comes to other items, such as mail, they are put out with a note saying to go through them and get rid of the stack.
I can be a pack rat but about once every 2-3 months the urge strikes to organize a closet....that is when things disappear.
