Why can't I toss things?

I been working at it for a couple hours and all I've managed to purge is one (small) box of scrapbook stuff. It is about the size of an LM order/priority mail box so that says a lot about how little I can part with. That's a couple hundred sheets of patterned paper, bunch of yarn from my fiber obession days, and a few miscellaneous items I'm RAKing on LM. Must be pretty crappy stuff since no one has taken them off my hands, lol. Back to work. Hopefully, I'll have more to donate and more to RAK soon.
