There is so much to go through.      A Dear Reader is packing up a lifetime.      There is so much to give away, to sell, to find a home for, and sometimes to just let go.      There’s the dining room table, the scene of a lifetime of joyous gatherings. None of her kids have the room or the need. Such tough choices      And so, she will let it go.      There are the folders and file cabinets.
