I don't think I have one. I'd be really upset if someone took my laptop or my games consoles but they're replaceable and most of my stuff is backed up. I think maybe my watch and charm bracelet. I'd freak if I lost them because they're really important to me. I also have one of my grandma's rings but I think I lost it but maybe it's just been left back in the UK I certainly didn't have it here in Aus.
