About two years ago, my 4-month old kitten Roo used to play “fetch.”
I threw my wife’s ponytail hairband down the hallway, and Roo would run after it, put it in his mouth, and bring it back to me.
We played this game dozens and dozens of times.
But after about a month or two, he evolved; he realized he wasn’t a dog; he was a cat—and cats don’t play fetch!
I can evolve too.
