I sat in on my first meeting that was held mostly in Arabic today where I was only able to pick up the odd English word was used instead. But I sat, listened, and watched, observing the reactions of the audience.

And then they laughed. They were all laughing.

What were they laughing about? Do I laugh too? Do I stare blankly into space?

What is the protocol for this?

So tell me – what would you do in a similar situation? To laugh or not to laugh?
