I have this problem with my DH. He thinks of things as just stuff and if its not broke, you dont need new. I must admit if felt weird to go through his towels and throw out the old yucky ones, but he ended up not being bothered. We have a standing joke in this house... it goes in the loft. Needless to say everything is up there. Including his old coffee pot that brewed cold coffee into a make shift pot. ( might need it someday... yeah right) One day it will get cleared out and on to the car boot sale.
