The good old X and 0s. Carrying the banners knots and crosses, a war was waged on a 3 by 3 grid.We fought tooth and nail for diagonal, vertical and horizontal supremacy. And when it was over, we played again. Best 2 out of 3, best 3 out of 5 and so on. But then the teacher would walk in and cut our competition short. Begrudgingly, we’d grant each other a ‘to be continued...’ status. It wasn’t over. It was never over.
