It doesn't matter how careful you are, marking things up when you dismantle them putting them in a place where you know you can find them again something always goes effing missing,
I believe that the "Fuck you up ghost" watches me when I am doing something, and then ether makes things go wrong or hides thing so I can never find them and then puts it back in the place that I have looked 10 times before, for the Misses to find
Hope they do turn up mate and you are mistaken £250 notes is a lot of money to loose, puts my Loosing two CV joint Circlips into perspective and I lost me rag over that
