My ex-husband was a hoarder - once when we were moving house a removal guy came and glanced around, gave us a quote. Then on moving day, when everything had come out from under beds, behind cupboards, under couches, down the sides of shelves, on top of bookcases etc. etc. etc......we needed 2 more enormous trucks, and they refused to move anything unless we paid them triple up front. Now (warning - amateur psychology on the way) I kinda associate hoarders with insecure childhoods??? Maybe??? There's a great feeling of lightness and relief when you get rid of junk, though. Nowadays I love the fact that I can look under a bed and see nothing but dustballs!
