I will karate-chop your FACE!

When I get scared, I instinctively throw my hands up in the "karate-chop" position. Like last night, I sensed danger so I dropped my laundry basket and went into Mortal Combat mode - hands up, crouching, alert eyes. I don't know why I do this. I like to think that in my past life, I was a trained assassin ninja. Yes, grasshoppa. That must be the reason.
