1. George goes to the golf course on Sunday morning. As he is teeing off at the eleventh hole, his golf ball veers toward a street next to the golf course and shatters a car's windshield.

1. Driving down a one-way street in the right direction, at no more than the posted speed limit, George hits a teenager, who is injured. The boy had jumped in front of George's car from behind a stone wall to impress friends by scaring George.

1. Driving on, at the next blind spot in the road, George honks his horn three times to warn any teenager who may be waiting to jump in front of his car. Two blocks away, an elderly woman believes the horn is an air raid siren and suffers a heart attack.
