Feeding-time on Parnell Square

A couple sit on a step. I see them from the bus. What had started as a chimpanzee-style grooming session has now progressed into a full-blown medical examination. She stares in his ear, tugs on his chin, has now pulled down his collar inspecting his neck, his chest. What is going on? It's about as gentle as a crocodile's mealtime and the guy does not look happy. Dublin on a sunny afternoon.
