Consider this, laydeez!
3 years ago, 30 years after I first left home, DH, DS and I moved back in with my Aged Mama. Yup, it's my childhood home as well, complete with my dollies and 1960s schoolbooks books in the attic.
DM and lovely DF (who died nearly 20 years ago) were both born in the 1920s and from the wartime/rationing generation. When we moved in, nothing had been thrown out for 20 years and nothing had been renovated/decorated or repaired for 30 years. It's a v.v. large house with masses of storage space. I can relate to EVERY ONE of the above posts! 
It still drives me dotty - the saving of crisp packets, the mouldy shite in the fridge, the hoarding of, well, everything that can possibly be hoarded
- and the obstinate absolute refusal to engage with any post-1960s technology, (such as cassette players and VCRs anyone?) far less 21st century witchcraft such as mobile phones and DVDs
.
Sadly, Mum is becoming v. frail and forgetful, so the balance of power has shifted. She can't remember what she's put in the fridge so I can swoop and discard without too much grief. We can also insist that houshold stuff gets repaired/replaced now on Elf and Safety grounds because DH does a good line in Pseudo-Authoritative 1950s Bloke-Talk which generates a sort of Pavlovian-Submissive response. (She won't listen to me because I am, apparently, still only about 15 and hormonal. I am really 51 and menopausal, but whatever.)
