Look, I admire your courage. I would hesitate to steal something from a guy who is celebrating his anniversary with his entire martial arts club. Of course, you did wait until I forgot my backpack, and grabbed the camera and iPhone that I stupidly had left in the top pocket (where I normally never leave them, because of scumbags like you), but still - you couldn't know that nobody was going to catch you in flagranti. And, as I am sure you know, every martial artist is secretly itching to know how applicable all that stuff he has learned over the years is in a real fight. But you took heart, made the plunge, and got away with your loot. Lucky you! Have fun with my iPhone - I certainly did, it was one of the best toys I have ever owned. The Casio Exilim is also a sweet little camera, even though the image stabilisation system was broken.
A word of caution though: You might want to return to the scene of the crime, for an eventual repeat performance. Who knows what else there is to grab? Resist this temptation, because if one of us Võ-Sinh (i.e. practicians of Võ Vietnam) sees you, retribution will be swift in coming, violent and prolonged.
