When I was little, mommy taught me to ring a bell when I needed to go potty outside instead of scratching at the door. I don't always use this how I am supposed to though! I sometimes just want to go outside to see what is going on so, I ring the bell to get out of the house. If mommy and daddy ask me if I want to go for a walk or a car ride, I go to the bell and ring it continuously while they are putting on their shoes. They think it is so funny when I do this.
