I believe most of my clutter has a purpose. Speaking of a "particular other," my ex-wife was an actual hoarder and the difference was that she would just buy/bring home stuff "because she had to" but she had little idea as to what she had, or where something might be. And that was ultimately a large part of why we are no longer a couple.

I think we just have to understand who we are, and then figure out ways to make that work for us, in the best possible way.
