Over the course of the three-day conference I had been allocated three different bedrooms. This was so confusing that I couldn’t remember where I had left my yellow cycling helmet.

The situation was more complex now that graduate SG dropped his room key into my bag and mouthed the number 614.

‘When?’ I asked under my breath.

‘4pm’, he whispered in reply.

It was highly likely that other delegates had witnessed our close proximity over the past couple of days. This afternoon, for example, I had been leaning against him at the back of the hall rather than sitting in a seat. Anyone who caught the key drop would have a clear idea of our intentions.

However, I was not worried about accusations of marital infidelity. It was the risk of contracting Red Hat Disease from SG that really scared me.
