side note - take some time and see if there is anything else of your parents' things that you would like if they get rid of them, and also things you would like if they pass on. My mother actually put my name on the back of a large framed mirror they have had forever; saying that I want it if they ever get rid of it. My sister wants the old roll-top desk where mother taught her to read.
We made this part of our "end of life" conversation with them about where their papers are, last wishes, funeral preferences, ect.
