My grandad always wore a hat, too. But he'd be 123years old now if he was still alive so probably not very relevant!
I was in Cornwall in June, Durhamjen, and saw no doffing. Or hats, except for sunhats, which definitely weren't doffed.
Ditto Gloucestershire but it was raining there so sunhats were not in evidence though umbrellas were.
I live in an area frequented by various members of the royal family and they don't put on airs and graces. My young daughter's friends were out hillwalking this summer when a dog ran over to them. A lone walker called the dog to heel and apologised as they passed by. The girls walked on and then it dawned on them that it was in fact the queen. She was on her own, tramping the hills and exercising her dogs, though no doubt security was lurking somewhere. My mum is a year younger than the queen but I'm not sure I'd want her wandering the hills alone!
I've also flown on a normal domestic flight with Camilla as a fellow passenger. She was wearing a coat that I wouldn't have thought fit for my dog to sleep on. They seem very ordinary human beings, really. I actually thought Camilla was someone who worked in my local surgery, because her face was familiar!
