Your old school exercise books? No - my mum did, and gave them to me. I had a moment of revelation, and realised that I was holding onto the DC’s exercise books, and if I was ambivalent about keeping mine, why was I keeping theirs? So I had a leaf through and then chucked them all
Text books from uni? No - all textbooks from uni will be out of date in my subject now as the law has largely moved on.
Story books from your childhood? Some, but hardly any. I think I still have the St Clare’s and Malory Towers series, as they were my favourites, but that’s it. I was a prolific reader as a kid, these books would have been a teeny percentage of what I had.
Your kids' clothes? I’ve kept the outfit they came home from hospital in (just sleepsuits), and a couple of tops that they absolutely loved. But that’s it. I keep DC1’s things for Dc2, but as soon as dc2 outgrows them, I either donate or recycle.
Artwork / handicrafts made by kids? I posted upthread about this - I keep a A3 portfolio folder per child per academic year and in it goes their best bits. Now that Dc1 is at secondary, there isn’t much to go in the folder!
Your DCs old school exercise books? None of them
Christmas and birthday cards? I used to keep the previous year’s Christmas cards. I think it was so that I knew that I’d someone died in the year (I know this sounds morbid), I would still have a Christmas card from them the following Christmas. But when I did suffer losses, I didn’t get their cards out that Christmas, so I stopped keeping them. Birthday cards - I have kept the first birthday cards when Dc turned 1, but no others. Again, I used to, but I’ve stopped.
Sentimental stuff e.g. cinema tickets, letters from friends, handmade gifts etc.? I don’t, but I can understand keeping these things as long as they don’t take up huge amounts of space. Same with your collection of theatre programmes and things like this.
Jewellery you don't wear anymore? Yes, but not really tatty or dates costume jewellery. I do keep some costume jewellery that I don’t wear anymore, but nothing tarnished or really dated
Clothes that you're too fat for? I posted upthread about this as this is my nemesis
Old bank statements? No, as they’re available online and we don’t get paper statements anymore
Letters from HMRC etc.? Yes, they’re also useful as proof of address. But I don’t have loads
Things "just in case" (e.g. 5 hole punchers)? I have plenty of this kind of thing eg staplers, elastic bands, bulldog clips, tape etc. I don’t have five, but I have one hole puncher upstairs in the study and another downstairs in the kitchen. That’s plenty i think!
Loads of books? I posted upthread about this. I don’t keep loads but Dh does, they are his nemesis
Pens - I have a small pot in the kitchen and another upstairs in the study. I have chucked those that I don’t like using and kept the ones that I do, making sure that I have different types eg biro to write on freezer bags, sharpie to write on plant identifying sticks, roller balls to write on anything else. But I only keep the pens I like using, not tatty ones
Car stuff - worth keeping if you plan to sell the car on
Order of service - I don’t keep these, I think I may have a copy of my own from my wedding in the attic with other wedding memorabilia
Birthday party invites - don’t keep anything along these lines
