When I was a little nipper I used to travel up from town to Gladstone School in Cathays. Totally unaided. There was a "little" guy, who always wore a mack. He was the angriest, most volatile person in the world. One day I was waiting on the bus stop, probably 9 years old. He came up behind me and offered to take on anyone who bothered me. He was shorter than me! The bus came I got on. As we drove past he was still shouting at people for no apparent reason.
