I have a place in the garage where I put things that have a sentimental value that would have been binned, stuff currently in that place:
A couple of old carbide lamps that my Dad had ever since I can remember
Other halfs first cars numberplate
An empty can of cider that was the first alcholol my Daughter ever drank
The number plate off my Dads last car
And old non stick baking tray that my other halfs Aunt scraped he hell out of wrecking the non stick coating.
An old hammer handle that broke off a hammer that I had used since I was a kid.
A piece of packaging off from my Daughters University set of pots and pans.
Plus others, as I say it is just stuff that has sentimental value to me and probably will end up in the bin when I pop my clogs.
