My baby sister is experiencing the same problem, even though she is much younger than me and has years of accumulation to catch up on. In email about plans for Christmas she wrote:
"We certainly do not need any more stuff,( if you know any people without stuff they can have some of ours,)"It occurred to me that a good family thing to do would be to help each other actually get rid of stuff. Maybe we could:
* help each other clean out the shed / bookshelf / liquor cabinet (yes, even my liquor cabinet is overfull).
* rent a skip
* bring a ute around and cart some stuff to a charity.
So the Christmas objective would be to end up with LESS stuff than before. That certainly works for me. Any ideas?
