Thanks to the miracle doctors at the QEQM, I was able to get out in the garden again yesterday.
While I was pulling up the weeds under the hedge at the front, I felt a sharp stabbing pain in my left thumb. On closer inspection, it seemed I had been jabbed by a syringe which had been dropped there, next to what looked like a cable tie. The syringe was marked 'insulin', so I can only assume some poor diabetic must have come over a bit queasy and had to inject themselves on the spot.
I do wish they'd take their paraphernalia home with them, though, and not just toss it in my garden.
