good sport socks

You win some, you lose some.
I had been teaching my grandson to play checkers. .
"It's important to be a good sport," I counselled.
"Oh, just a minute, I have to get my sport socks," he exclaimed, dashing over to the tree. He returned, his feet snugly outfitted in new socks.
The game continued with losses in both camps, but his eventual victory.
"These sport socks really helped," he enthused.
