As a devout Atheist, I had to do some research on this business of crossing fingers. Dubious online sources tell me the custom predates xianity; however, as part of my ongoing battle against foolish superstitions, and partly due to tendinitis, I regret to inform you that I will not be joining your other friends in their finger-crossing ritual. My best wishes, however, on positive results in your search for what some call "merciless employment."
