This morning, I received an e-mail, mistakenly sent to me by someone named "Gerry".
I replied, pointing out that, since I didn't recognise the name, perhaps they had sent it to me by mistake, unless I'd met them in a pub in Sydney, during which encounter I'd subsequently consumed far too many beers to remember them.
Gerry replied saying no, we'd not met in a pub in Sydney ... and asking whether I had, by any chance, run into someone named Trish Murphy. I have a feeling Gerry thinks Sydney is still a small colonial settlement :-).
