Do you have an accidental or intentional collection of something whose size has unwittingly crept up on you?
I collect pretty much everything.
I guess my biggest collection is of backup disks. I have disks going back to 1980, single sided single density 5.25 inch, up through the higher densities of 5.25 inch, to the 3.5inch floppys, to CDs, to DVDs. Must have somewhere near 30,000 disks in various boxes in the garage.
Prior to moving here to Kaikoura 15 years ago (a 300 mile move with a ferry trip across Cook Strait in it), I had three big sheds full of stuff I had collected. Some of that got sold, and much of it ended up in landfill (9 truck loads) – much to my distress.
Here I do not have much space, so have not collected much (Ailsa may have a different perspective on that 😉 ).
