I guess I’m a pack-rat too. I store everything away, even non-essential stuff. I’ll eventually go through the mess and throw away junkmail, spam, etc., but before then, it’s essential to...nothing. But I keep it, just in case... ;^)
I know, I’m also a pack rat, but there comes a time when I NEED to make room, then I throw out stuff. Roomey is worse than I am.
