It must start at an early age.....A friends newly licensed teen age son drove himself to the dentist's office, a place he had been to his entire life. He couldn't figure out how to get out of the parking lot because the way he came in was a one way street going the wrong way! Had to call his mom to get directions to get out of the parking lot! It never occurred to him to look behind to see the other one way street going in the direction he wanted to go!
