I had a nice thing happen to me the other day. I work in a building that has ten floors. I've been at that particular job for the last five years and during that time, you get to recognise others who work in the same building.
The other day I was going to get a sandwich for lunch and took the lift (the stairs are only legally used as a fire escape. Just getting in before someone tells me that using the stairs is better for me!). I work on the seventh floor and at the sixth floor a man entered the lift.
"Gidday," he says, "how are you?"
"I'm fine," I reply. "How are you?"
"I wouldn't be dead for quids!" came the reply.
And from there we got talking. We walked out of the lift, out of the building, down the road and into the same coffee bar for our lunches, chatting madly all the while, as if we were old friends from way back.
No, I haven't seen him since, I have no idea who he is, but for that short space in time, we were old friends talking about our day and what was going on in the world.
It was the highlight of my day that two strangers could, for a brief moment, share a friendship. We may never see each other again, but for me, it's something I will treasure. One of those serendipitous things that happen every so often with a complete stranger.
