Gosh, too many things! But I have started purging a lot. I still have my mother's high school diploma and a pocket knife of my grandfather's and my grandmother's pearl necklace (I wore it at my wedding). I don't think my children will treasure them like I do.
I have a mixing bowl that was my grandmothers. It has a crack in it and is discolored. To fragile to use,but once in awhile I put a few pieces of fresh fruit in it just so I can stand it on my kitchen counter top. It brings back wonderful memories of her using it.
