Caught!
Because I speak French I can eavesdrop on them, which is easy to do because they believe they are the only ones in the area to understand the language and so they speak freely, intimately, and without reserve. It was because of this that I once shared an elevator with a a young couple who were discussing how they could cheat on their taxes. Surprised, I turn around to get a closer look at them but my face must of seemed too alert for the casual glance i had thought I was mastering, their eyes widened in response like scared owls and they whispered for the remaining floors.
