If you were just sitting, they would assume you were resting.

My little story today: I ride with a bandanna tied around my wrist for mopping sweat, etc. Today it blew off and was sitting in the middle of the highway. I stopped, laid down the bike to run back and get it. A car stopped, blocking traffic so it wouldn't get run over. Wasn't that nice? And it was my good orange one that Meg gave me.
