I was about to take a picture of the box where all the relevant bits of paper live for when the tax form comes - and then realised there was something so much a part of my life for so many years that it was a much better illustration for the subject.
Yes - I can hear you all going What the heck? Wombat has gone mad!
Let me explain. I bought this painted mirror (very fashionable at the time!) with the tax rebate from my first job. It has moved with me every time since - a period of, uh, over 30 years - and has hung in our entrance, opposite the door into the living room, ever since we moved into this house over 20 years ago.
And so, as tax rebates go, it has been very long-lived!
