MiL is. They are downsizing soon. All their married life they have had to buy bigger and bigger houses to accommodate her various hobbies, more and more sheds. Now they can't cope with their huge house and garden, even with a gardener. FiL says that he is going to have to pay around £5000 a year just on a storage facilty because MiL gets tearful at the thought of parting with her stuff. She was teacher until she was 50 and she has kept every. single. item. that every child ever gave her - even though he can't remember who gave her what. A whol cabinet of photos from when she thought she might be a photographer. An industrial papermaker. More seeds than Kew have in their cold store. (never managed to get a decent garden going in her life) Dressmaking stuff. Art materials - she is a pretty good artist, but has kept every single sketch ever. At least a ton of pencils. 3000 books (she counted) left after they had a big cull and donated the rest to the local library. Hundreds of cookery books and implements but is incapable of cooking from scratch. Several sets of china, ditto of cutlery. Many millions of ancient towels, duvets and so on - in fact they have three lofts, one is filled with shelving units full of bedding.
They have freezers and fridges in their massive garages. When they pile so many ancient cars into the garage that they can no longer get to the freezers at the back, they add to the chaos by buying more fridges and freezers. Her FB page this week advertises three freezers for sale. How they will get them out I cannot imagine, but I suppose it's a start - however I wouldn't want to be the first to open the door as I know for a fact that no-one could get to one five xmasses ago and we had to go without the brandy sauce that she had made months previously!
As for old clothes - everything since the 80s, I think and a few from the 70s. They have at least 8 wardrobes.
FiL collects organs, of the playing variety. He is leaving one up in a loft as a surprise present for the next owner. No small item, this. He collects wooden puzzles of amazing intricacy, and jigsaws. And trains, and railways.
With them as role models, it's not surprising that I have had the odd spat with DBH. Our first row was over an old board game that no-one ever played but he refused to let me clear it out. It has never been touched, in the 20 years we have been together, along with half a dozen others.
