Do you have a piece of beaded jewelry that you don't wear? Maybe it's out of date, or it's broken. It might be too small for you, or too big or heavy. Or there are a few nice beads, but the whole thing is...well, it's ugly.
But you just can't bear to get rid of it. The piece evokes wonderful memories of someone you loved who wore it, or your own memories of a treasured time when you wore it yourself, or of someone who gave it to you.
