I remember being at Caernarfon Castle for the investiture of the Prince of Wales in 1969. We were on holiday at the time and the weather was scorching. I hated that day. I had very sunburned shoulders and, since I was only 10, I was squashed by the crowds of people who came to witness the spectacle. All I remember of the day was the searing pain as people pushed past me. It was horrible.
