As a child of 10 or so, I admired my father’s ability to wiggle his ears. I wanted very badly to do the same. At first I could not. So I just sat there for hours, sometimes while watching television, just telling my brain to get going and start moving my ears.
I guess “sat there for hours” means in this sentence that Steve kept trying to wiggle his ears. Am I OK? Is it a kind of idioms?
