Had a roommate one time whose most prized possession was a cocktail napkin bearing the autographs of all the members of the legendary band --- wait for it -- Night Ranger!!!!!! (Remember "Sister Christian"?) That was maybe when it started for me. Don't get me started on gold or diamonds --I have a whole separate rant about why these are valuable in modern society-- I mean, why are they valuable? It's cuz they're SHINY! Kinda primitive if you ask me.
