Anyway, I had an experience today when I visited a local animal Park to view a couple of new arrivals. I will say that the children and families I encountered were normal courteous people, but with one glaring exception. I encountered a child (a girl of around five years old) who was literally screaming at the top of her lungs every few seconds for absolutely no reason - I'd heard her from the car park on my way in. It was clearly an ingrained habit. As my visit got underway I encountered this child who let out one of these screams about 5 feet away from me and it was literally agonising, given the decibel and frequency rating. I yelped and clamped my hands over my ears, and one of the parents who saw my reaction gave the child a mild reprimand which the kid totally ignored. I carried on walking but the screaming followed. It was doing my head in. I couldn't see the parents anywhere in sight, so I walked up to the child and gave her a stern glare. She got the message instantly and didn't shriek again. But I spent the rest of my afternoon with a dull pounding pain and a ringing noise in my right ear - which is still giving me discomfort.
