Towards the end of the reception, I could see - out of the corner of my eye - that his wife of 63 years appeared a little tired and distracted. A couple of minutes later I noticed that she had moved on but left a wine glass on a table, and wondered if she had abandoned it deliberately or forgotten it.
The next time I turned round though, I realised I wasn't the only tracker in the room. Spike, her grandson, had materialised and was sitting next to her chatting in front of a screen showing old family photos. She visibly bloomed in his company. Simultaneously and independently Sophie, her granddaughter, picked up the forgotten glass and brought it over. Moments later they were all smiling together.
If I ever need a Close Protection Team, I am going to get those two some weapons and martial arts training and employ them. Their peripheral awareness, plus ability to perceive and defuse risks are already off the charts.
