I try to go to the gym just about every morning. Because I work out with my scarf on, people stare - just as they do on the streets of Cambridge.

The other day, though, I felt more self-conscious than usual. Every television in the gym highlighted some aspect of America's conflict with the Muslim world: the war in Iraq, allegations that American soldiers had desecrated the Koran, prisoner abuse at Guantánamo Bay, President Bush urging support of the Patriot Act. The stares just intensified my alienation as an Arab Muslim in what is supposed to be my country. I was not sure if the blood rushing to my head was caused by the elliptical trainer or by the news coverage.

Frustrated and angry, I moved to another part of the gym. I got on a treadmill and started running as hard as I could. As sweat dripped down my face, I reached for my towel, accidentally dropping my keys in the process. It was a small thing, I know, but as they slid down the rolling belt and fell to the carpet, my faith in the United States seemed to fall with them. I did not care to pick them up. I wanted to keep running.

Suddenly a man, out of breath, but still smiling and friendly, tapped me on my shoulder and said, "Ma'am, here are your keys." It was Al Gore, former vice president of the United States. Mr. Gore had gotten off his machine behind me, picked up my keys, handed them to me and then resumed his workout.

It was nothing more than a kind gesture, but at that moment Mr. Gore's act represented all that I yearned for - acceptance and acknowledgment.

There in front of me, he stood for a part of America that has not made itself well known to 10 million Arab and Muslim-Americans, many of whom are becoming increasingly withdrawn and reclusive because of the everyday hostility they feel.
