I was attempting – and failing – to run a one-day conference without any help. By 3pm the delegates had completed their activities and were bored and fidgety, but I couldn’t deal with them because someone had left a door open at the back of the hall and strangers were using the conference venue as a thoroughfare.

Then a whole host of new delegates arrived! How would I cope? Thank goodness that CI was among them and soon set to work allocating badges to the new arrivals.

With CI in charge I now had the chance to leave the venue for a short break. Outside in the street I found something strange in my hair. It felt like a seed, so I pulled it from my head, and broke its shell in the process. I was completely unprepared for what happened next: I watched in horror as thousands of nit-like insects escaped into the open.
