I know mate... it's really tricky. When my best mate died all his stuff went to his daughter, which is right and proper but there's a few small things there that have a lot of significance to me and have special memories that I would love to have around me.
It has made me start asking my friends though 'If I go, is there anything that is special to you and you would like?' ... it's a bit morbid and people don't like talking about it, but I now have a list of stuff that will go to my friends if anything happens to me. The odd record that they were there at the gig when I bought it, or a picture that I took while we were at a festival, a guitar pedal that I made while we were in a band together... just little things like that, and I want them to have them.
