i've collected many Atomic particles
if i had any collecting obsessions, i went thro' them fairly quickly too.
my mum said i collected carrier bags, but i'm sure i didn't, it's just easier to squeaze them all into one box than rather than taking a stupid cheap piece of plastic half way across the house to throw it away! i could squeaze a hundred carrier bags into any box, i'm sure! i've seen many more OCD people collecting many more carrier bags than i ever did, or do they call that recycling these days!
everyone has collections of some sort, and could easily be said to be obsessive...
