I thought of your Sunday 7 yesterday, when I was having a fit of "not me" and getting rid of things I've been carrying now for (counts back) 3 moves, for reasons sentimental or pragmatic, and yet never actually used.

Mostly they were gifts given by people who didn't have a clue what I liked... but some of them were things I picked up and thought "I could use this" and then never really did.

(fortunately, I had friends over who tended to go "OMG, you're getting rid of that?" every so often, and so I was able to regift rather than toss, which eased the guilt a little)
