I was having a run at the Y.
A man with a red tipped white cane found his way to the treadmill next to mine. He folded up his cane, an employee assisted him with pushing buttons to get the machine started, and then he was running along next to me.
Then he started to laugh. And then he laughed harder. He was running and laughing and it was contagious and I began to laugh. And the man on the other side of him began to laugh. And the three of us ran, and laughed, and ran. And then he yelled, still laughing, "I USUALLY CAN'T RUN!" And we all laughed harder still, and cried too.
It was the best run of my life, and I still think of him sometimes when I'm out for some exercise and I appreciate how great it feels to just run.
