This was on the beach at Barmouth a couple of years ago.
Nick and his daughter went for a swim in the sea, Ian had his dog with him and went walkabout, so I was guarding the heap of beach stuff.
I decided to make a sandcastle to while away the time in pointless activity, and realised as its boundaries grew that some of the boulders nearby would fit very nicely into the bucket, with a bit of room all round for sand.
So once we'd left it behind, the first nasty little sod who ran past, barefoot, and took a good, hefty kick at my sandcastle, would find themselves with broken toes. Heh heh heh.
Ian and dog were back by then. I revealed what I'd done, and such was Ian's approval he took the bag of fresh dogshit he'd been carrying, dug a hole not far from the castle, buried the turds, marked the spot with an X, and wrote 'BURIED TREASURE' in the sand with an arrow pointing to it.

Were were both in our mid-30s and, obviously, without children of our own.
