I will admit I hoard ... but no where near as bad as that! I do go through my stuff and declutter and downsize often ... but it's amazing how quickly things accumulate.
And no, I am not one that goes out looking for stuff and figuring out how I could use it ... mine is mainly papers, kids school stuff, books, etc.
My mom though, does a have a room that you can't walk into. And my dad & stepmom ... they are the ones that search second hand/thrift shops and think they could use something ... and then it sits there forever and nothing ever gets done with it. You can't walk in their basement without having to walk around mountains of crap, their bedrooms/hallways/bathroom/kitchen are getting just as bad. Definitely not a kid friendly house (thankfully, my mom only has the one room, so it's not hard to keep the kids out of the stuff, but my dad's house ... ugh). Needless to say, I have issues being in my parents houses. Des can't stand it. But at least I come by it honestly. lol
