when i was in grade 2, and my class was on a field trip, we saw a woman drop her purse as she was waiting for a street car. Without looking she bent over into oncoming traffic and her head was struck by an ambulance...
I was too young for the irony...

Also, driving out east, my dad and I saw a little pick-up truck on fire on the side of the highway. When we stopped, to see if we could help in any way, we discovered the owners in their attached trailer with no idea that their truck had caught fire. Odd thing seeing a car go up in flames...nearly had a heart attack when the tires started exploding...a fire truck got there before the whole thing exploded though...
