I just walked from the office to Tesco to buy my lunch. On the way, I was passed by a large group of people I recognised as from my company, heading in the other direction. As they approached, I could hear them chattering to each other, but couldn't hear any of the actual words in the conversation.

As they neared me, the conversation suddenly seemed to encounter a lull, and they all went quiet. Then, just as they passed me, one of them said, quite clearly and distinctly, ‘Frobbing trout’. As they went off into the distance, their conversation started up again.

I probably don't want to know what that was about, really. But suggestions from my readers will probably be amusing :-)
