Yesterday, I was out.

I saw a New Jersey license plate.

I had to go home.

Why would this happen?

Richard's way of getting through the day. When he sees a NJ plate he has to go home to a family who doesn't understand him.

Speaking of license plates how can Wally take a car home for a week and drive it without license, registration and insurance. (Wally Buys a Car) Wouldn't the car dealership be responsible if he had an accident?
