No matter how materialistic you may or may not be, there is a very large possibility that you have some object in your house (toy, books, or any other miscellany) that, although it has not been used since ages, you simply do not want to get rid of it it is because of the affective value this has, or because something tells you that "this object will still be useful in the future', eheheh
What would that be to you?
I have an unjustifiable appreciation for the 2 Hot Wheels that they gave me 10 years ago, a Monopoly box and hundreds of shredded comics! I rarely use or read or play with them but giving them to others who would make better use of them or selling them are very radical possibilities and that would certainly make me regret it seconds later.
