Plague fair

 “There are no constant friends and no constant enemies, only interests are constant” – Winston Churchill.

A silver airbus landed at Heathrow Airport. The London air was moist and fresh.

– Solomon Grande? – the British border officer read in the passport, – the purpose of your visit?

– Business. To participate in a scientific congress.

– Are you a scientist? In what field?

– Actually, I'm an infectious disease doctor, a plague specialist. We will have a conference here on this topic.

The officer slapped the stamp in the passport. The way to the country was open.
