FRUSTRATION

I've been trying to clean my apartment the whole morning, but I am getting more and more frustrated. The clutter here is unbelivable. I live in my grand-parents old apartment and I still have most of their stuff (they bought it in 1941) packed together with my stuff. I do not have a heart to throw their things away, but since my dad and my aunties are showing no intrest to their heirlooms, I probably have to. I simply can NOT throw away over 400 old books... Anyone interested ??? Old paintings ??? Coffee cups ???
