The other day I was held at sword-point in my home by a masked bandit. After I unsuccessfully plead my loyalties and allegiance to his cause (because we didn't speak the same language), he began to quiz me on my Spanish. Through clenched teeth he demanded: "How do you say 'bed'?", "How do you say 'school'?", "How do you say 'friend'?". After I answered each question correctly, the masked bandit put away his sword and stated, "Good. Now I won't kill you!" and walked away.
I wiped the sweat from my brow and thanked my lucky stars that my pre-schooler just so happened to have learned those words this year, and just so happened to have shared them with me. That's what I call fortuosity!
