The second wall of the box was speeding. The third wall was being out late at night. The fourth and final wall was no seat belt. Alcohol, speed, late night, no seatbelts all closed in on her to create a dangerous situation, a dangerous box to be in, for anyone.

They hear of the deaths of others but never believe it could happen to them. Despite her fame, riches, poise, popularity and position, she could not survive in the box she entered that night. I look across the table into my daughters' faces. If it could happen to her, it could happen to you. I make a few more points and the lecture is over.
