We have been living in London for 12 years. Being prudent (and hasn't THAT word gained some overtones in the past couple of years!!) people we have kept all our paperwork during that time.
Now we are moving on we can't see the use for our 12 year old phone bills, bank statements and payslips, so we have bought a shredder and are busy making packing materials. This has been rather a liberating experience, especially when it comes to letters from the tax office. This has been the best part of packing to leave for France, all the rest of it is hard work and stressful and we are not enjoying spending our long weekend (and the coming week) up to our necks in cardboard boxes.
We now have 5 or 6 bags of shredded paper to cushion our valuables (as it were), and then when we are in France we can compost it all for the garden. I am quite pleased with the concept of triple recycling, so will spend the next 15 seconds in "smug" mode.
