Sorting out and throwing away

Why is it so hard to throw things away? Whilst I was in Kenya my dad decorated my bedroom and so all my stuff was moved out and then back in again. Well, most of it was moved back in again but some stuff was left in my brother's room for me to sort through on my return. It was great actually, I went away and came back to a tidyer, newly decorated, clutter-free room and I hadn't had to do anything about it!! Today is sorting out day, though, and what junk I have kept! When I moved out of halls and into a house at college I boxed a lot of stuff up into shoe boxes that never actually found their way out of the shoe boxes into new homes. When I graduated and moved back home the shoe boxes came with me and found a new home on the top of my wardrobe. Going through them now I wonder why on earth I have carted so much junk around from house to house! Some things I can't throw away though, like the teeth I had extracted before I had my brace put on (fantastic roots, I'll have to get them out in school some day!), or cards from various classes that I have been on placement in. Other things I'm thinking, will I ever actually need this again? Probably not, throw it away. And yet more things distract me from my sorting out process, like school reports from when I was still at primary school... always fun to read!
