My Mother & Father split when I was around the toddling age.
Prior to the split, I'd apparently watched Dad paper over my Trumpton Town wall-paper with something else. I knew where all of the fire engines were and the next time my room got visited, the new paper was peeled back to reveal all of them!
Growing up presented opportunities to progress from eating boogers, plants & soil, to exploring the home surroundings.
That is when I found the shed in the back yard. And the tins of paint stored safely within. I still don't know how I managed to get them opened, but I did and the contents were strewn everywhere.... walls, yard, my wheel-barrow and my clothes... recently bought clothes.
Some time later, in the same shed, at the back, I came across a large sack of curious items.
Small cylindrical metallic shapes with a plastic ring around the outside. And a hammer.
The plastic rings were different colours and some of the 'cylinders' gave off a bigger bang when hit with the hammer, but I can't truly recall which gave the best bang... maybe it was the green ones??
It was only later in life that I discovered what they were likely to have been. My Dad had done some construction work and I suspect that they were probably Hilti cartridges.
The pock-marks are still there in the concrete of my Mum's yard.
Regards.
