The robin spent the first few hours of his day finding and eating his first meal, then went, as he did most days, to visit the true king of his territory. The king displayed his power to his subjects by allowing the young ones (along with a few of their parents) to cross the road he chose to stand on whilst all the humans in cars stopped and watched. After everyone had shown their proper respect to him, he would leave. The robin was always impressed by this, and considered this human to be his role model.

A little later that day he was flying over a garden when he heard and saw two humans singing loudly at each other. He had once thought this was a mating ritual, but realised now it was actually a territorial dispute. Usually one would sing louder and longer than the other and the quieter one would go back inside the building, leaving the louder singer to claim the garden as their territory. On this day, it was the smaller (female, perhaps?) human that sang for the longest and the bigger one who retreated. Good for her.

A few houses away, he saw another two humans standing in a garden doing one of their strangest activities – sharing food. He had seen this many times before – they would put their mouths together and seemingly lick each other’s teeth. The robin had had a mate before and had shared the occasional worm with her, but their beaks never got this close together. When humans cleaned food off each other’s teeth, they were often really thorough about it. The robin could never tell which of the humans was sharing their food with the other, or if they were both sharing their food at the same time, or if they were just generally cleaning each other’s teeth. Whatever the case, the amount of time they spent on this activity made the robin glad that robins did not have teeth.

Oh, but this was far from being the strangest human activity the robin had witnessed.

What was the strangest human activity the robin had ever witnessed?

How might the robin misunderstand what he saw?

How will the story end?
