Cleaning...an appropriate thing for an Untidy Corner

As one recently graduated from college and thus thrust back again into the lap of my parents, I have had call to do some cleaning.  I love a clean house and/or room.  I really do.  My work spaces have always been quiet tidy.  My bedrooms....never?  Unless we count mandatory room inspections in my high school dorm and childhood chores--I was very fearful respectful of adults that way.  Anyway, enough lame introductions.  The point is, while cleaning and sorting mine items, I realized just how many things I'd forgotten.  Nothing major, just little memories attached to small junk-worthy stuff.  I'm at a loss.  Should I throw the stuff out?  These aren't life-changing memories, and the actual stuff isn't anything I want to keep.  There's just some sad about throwing out memories.
