You're at a popular landmark in your town, the Gateway Arch. Feeling someone staring at you, you turn and spot someone looking at you from a distance.

The guy looks away after a moment, pretending to be looking at his map after being caught staring.

Even after he looks away, you study him, noticing he's not very dressed for the rather chilly weather. In fact, he's in... shorts, giving away that he is clearly a tourist.
