When we moved in 2013 we carried out the promise we made each other when we had had to clear my parents¨ house after my father's death in 2009.
It was brutally straightforward: only to keep things that were in use, or had great sentimental value, or that we realistically foresaw a need for in the IMMEDIATE future.
The few years that passed after burning 25 years of Inland revenue forms, receipts, old Christmas cards received from friends and equally old ones that had never been used, plus a dress suit from before the second World War, a St Andrew's University undergraduate's gown etc. etc. etc. made us relatively hard-hearted when it came to our own stuff.
Since we moved, I destroy the four year old receipts and tax papers at new year, when the financial year ends here, and I put the new lot away.
We have stopped buying "stuff" because it would be nice to have, limit ourselves to one new Christmas bauble or Easter decoration a year and only keep books we know we will re-read.
I have also gone through old photograph albums, passed those from my father's side of the family on to my cousins on that side who have children who are interested in old photos of relations they never knew. Photos from my mother's family have been culled, as no-one will want them after I am gone.
I regularly estimate how many old jam jars I need, as it took three or four trips to the nearest bottle bank to dispose of those my mother had kept for years after she stopped jam-making, and heresy of all heresies in my family THROW THE REST OUT (recycle them).
Like everything else, starting is hard, especially if you do it immediately after a bereavement, but the process does become easier once you get used to seriously considering what you need or really want to keep.
