You're driving on the road and suddenly decide to dig your nose since you don't think that anyone can see you. Someone is rude to you on the road. It enrages you so you tail the car and follow it wherever it goes for the next few minutes. Someone is upset because you switched lanes in front of them. You just ignore the driver and remain calm.
Someone quickly makes a left turn.
You slam on your brakes just missing them. You're upset but soon calm down because you can instantly remember that no one is perfect. In fact you can remember doing the same thing before. A senior citizen is driving below the speed limit. You complain to your friend, who is in the passenger seat that senior citizens shouldn't be allowed to drive at all.
