By the way, in your nice safe neighbourhood do you therefore leave your doors open, keys in the car, notes on your front door of your whereabouts? Do you DEPEND on that safe neighbourhood?
In the small town where my mother lives, people do exactly that.
But if you lock your door and fasten your seatbelt, why is it then laziness to use a tsuba? I trust my partner's control, but I don't *depend* on it to protect my hands.
