Many times I have tried to start a collection. Probably my most successful one was a marble collection in primary school. There were some pretty awesome ones there. I made my own frosted ones by taking sandpaper to marbles that I didn't like that much. My favourites were a couple that my Granny gave me. I think they had belonged to my Dad or Uncle at some stage. They were cool with beautiful blue and chocolate coloured swirls inside.
Unfortunately after a while I forgot about it and lost it.
Nothing seems to really hold my interest long enough to make me pay enough attention to it to be a collection. I have large amounts of things that I've kept over the years, but I don't actually know what is in all the boxes I have at my parents house. It's not that I'm collecting things, I'm just too lazy to throw them away.
