From unnecessary to important. We throw our things away. What do we throw away? The things my ex-girlfriend gave to me for Christmas? I thought it was precious when I was in love with her. - but, when she dumped me, they lost their sentiment. So, I tossed them. But then, things that I am casting away, started screaming and yelling at me that they had a beautiful memory. Then I think twice. Is this really not important to me anymore? Or should I keep this memory that is a part of me? Everyone has very important things. The main ingredients of being "precious" is the relationship between the owner and the object.
