Ask questions about the history of things. There is a lot to learn. Get into the nitty gritty specifics. This can be fascinating.
My son and I were watching the Winnipeg Blue Bombers play their arch rivals the Saskatchewan Roughriders. He asked me why one team had their brand name (Blue Bombers) on the front of their jerseys while the other had their place name (Saskatchewan).
Then he queried why one was a city name and the other was a name of a province (great question!). I had no idea, so began reading about it online. A very interesting story, it was, especially when you add in the situation with the Rough Riders from Ottawa. The fact that both teams were also red and black added to the unusual tale. Look it up.
Backstories can be so interesting. Though, like anything, check different, and especially opposing sources, so you can triangulate around the truth.
