When you're in a small group standing around looking at bikes, consider doing what Dan's doing and stare mysteriously into the distance while everyone else is staring at the bike in front of you. This shows restraint and adds interest and mystery to the scene.
Andy is also demonstrating "The Teacher" technique as he is staring at his own bike and is available for questions. Note how all of this works together as a package and draws Rachel in to participate in the admiration of Andy's Sportster. This is a classic example of teamwork my friends. Well done.
