I was completely wrong. I came home one night last week to find that he'd completely cleared out the room, got rid of a load of stuff that had no particular use, rearranged the furniture, and basically completely transformed the place. When I'd got over my amazement, he explained that now the rest of the house was so tidy, he'd come to appreciate the order and serenity, which had inspired him to recreate the same in his room.
The moral of this tale is that even if you think you're on your own, the inevitable positive effects of decluttering and organising will improve the lives of those you live with - and they may be more well-disposed to it than you think.
we had not started decluttering in earnest this time last year, and we decorated in our usual style - named 'santa's grotto' by my mother. This style is dominated by basically putting every decoration you have up, going to the shop and buying some more, and putting those up too. I blithely approached decorating this year in the same way, without realising that I had gradually changed my environment and alongside it, my tolerance for 'stuff'.
We got a lovely tree (a rental - it's in a pot with soil, you water it, take care of it, and take it back to the farm in January. they put it back in the field, and you get the same one next year - a non-waste genius idea) and started decorating. Only, we got halfway through, and suddenly it was enough. I didn't want to put one more bauble on it. The same with the rest of the room. One paper chain sufficed, and a few ornaments around the fireplace. It's very far from minimalist of course (I'm an aspirational, rather than successful minimalist) but it's also a long way from the 'santa's grotto' I have loved until now. And even this amount of decoration is already starting to irritate me...
thanks for reading, and I hope your celebrations go well.
