And when I took my new skill home to try out on my younger sister, it didn't take long for me to beat her at that, too, as I did with checkers, Sorry!, and Fish. (She made me pay, of course, later, by teasing me until I slugged her, requiring our mother to whack me five times with the wooden spoon on my bare bottom, because there's no hitting in the house.)
I remember the girls kidding us, mercilessly, and some were really angry that we'd invaded their turf. And a couple tough guys sneered & called us sissies. But the girls we were playing were loving it, & put them down sharply, which got at least one of us beat up on the way home.
To me, though, the fun was in picking up something new, as shiny & sharp as a new jack, finding sudden joy in an unexpected place.
