Ah yes. I come from one of those families. And it's become apparent from cleaning our apartment recently to make room for registry gifts (yay!) that the boy also comes from the school of "don't throw anything away even if you do not use it because you never know when you might need it".
In purging out apartment, here are a few items we found:
+8 empty shoe boxes
+an entire trash can filled with coins. Seriously. Would I lie to you about that? I'm not even that creative to come up with that one.
+one figurine from Titan Quest
Me: What is this? (holds up figurine, with trash bag in other hand)
Him: That's Titan Quest! (grabs at figurine) Here, she can be the protector of the living room. (puts figurine on top of television)
+an entire shoe box filled with receipts from 2003
+a big pile of socks under the bed that the cat has taken over as her bed
+a photo of us on our 1-year dating anniversary in San Francisco. Awwwwwwwwww
We took quite a few bags to Salvation Army so we could welcome a few new items into our home:
[We made this dresser this weekend, and it was a big pain in the butt and some of the drawers are not the best, but it looks cute! That's our cat sniffing at my camera bag.]
