Explanation:

                   It is mentioned that Henry has had his driver's license for 2 months. He is 16 years old.

                  Having had his driving license, one night he and his friend decide to drive down his car along country roads while drinking beer and also decided to turn off the head lights of the car while driving and drive fast as they can.

                  This shows Henry's lack of responsibility as a citizen. Drinking and driving can lead to accident or can cause damage to properties. Moreover driving with headlights off is more irresponsible act committed by Henry. At night it is dark all around and Henry can hit any person moving on the road or any animal that tries to crosses the road.
