Wavewright, that's just shocking. I'm glad you're all right.
I've had an odd pairing of events over the last two days.
Yesterday I was heading home by tram when I chanced to see a young woman who was apparently sitting on a Myki card (our variant of an Oyster card). I asked her if the card was hers and yes, it was, it had fallen from her pocket! So that ended well.
Today I was returning home from a doctor's appointment. I was sitting at the far end of the tram, behind a trio of young students who were talking at length about esoteric subjects (Heisenberg's Uncertainty Principle was mentioned, and the discussion turned to the question of making an accurate simulation of the Universe). A few minutes later, after the students had left the tram, I changed seats, and saw a small leather wallet on the seat where the students had been sitting. I picked it up and found that it was crammed with IDs of different kinds; driving licence, student card, Medicare, and others. Thinking that the owner would be panicking when he found out the wallet was missing, I searched through it but found no contact number. I gave it to the tram driver to hand in, but first I took a snap of the licence, and when I got home, I googled for the name, which was an unusual one, and found a Facebook page. So I sent an IM that I'd handed the wallet in and the owner replied promptly expressing his relief.
Losing your ID in these days would be a nightmare; I'm glad I was able to get it back to him quickly.
