@EstoyRobandoSuCasa I liked the phrase "woe betide", although I didn't mistake it for somebody's name. I first saw it in the Ladybird book of The Sorcerer's Apprentice. "As my apprentice, you must keep my cauldron filled to the brim, and woe betide you if I find it empty!"
@MonaChopsis With "traffic light men", I was fascinated by traffic lights from a young age, and in my time, there were still some on the black and white poles, which had the word "Stop" in the red light. I was amazed to learn later that lights do actually detect where the cars are, and change the lights accordingly. When I was older, I could spend ages watching them, and predicting when they would change.
Another childhood thing which I pondered deeply was wearing shoes on bare feet. I liked the feel, especially of trainers, noticed even at age five that I stopped "feeling" them after a while, and it was odd that my parents didn't approve of being sockless, yet at school, we were made to put shoes on without socks to walk to the assembly hall for PE, which we did barefoot.
I often wondered what it was like to be in a cage, locked up like an animal, or Hansel. I found out when I crawled into a dog cage in somebody else's house, and one of the older kids saw me there, and locked me in. He thought he was being mean, but I loved it!
