was a freshman in college when I met the Whites. They were completely different
from my own family, yet I felt at home with them immediately. Jane White and I
became friends at school, and her family welcomed me like a long-lost cousin.
In
my family, it was always important to place blame when anything bad happened.
“Who
did this?” my mother would scream about a dirty kitchen.
“This
is all your fault, Katharine, ”my father would insist when the cat got out or
the dishwasher broke.
From
the time we were little, my sister, brothers and I told on each other. We set a
place for blame at the dinner table.
But
the Whites didn’t worry about who had done what. They picked up the pieces and
moved on with their lives. The beauty of this was driven home to me the summer
Jane died.
In
July, the White sisters and I decided to take a car trip from their home in
Florida to New York. The two older sisters, Sarah and Jane, were college
students, and the youngest, Amy, had recently turned sixteen. Proud of having a
new driver's license(驾照),Amy was excited about practicing
her driving on the trip. She showed off her license to everyone she met.
The
big sisters shared the driving of Sarah’s new car during the first part of the
trip, but when they reached less crowded areas, they let Amy take over.
Somewhere in South Carolina, we pulled off the highway to eat. After lunch, Amy
got behind the wheel. She came to a crossroads with a stop sign. Whether she
was nervous or just didn’t see the sign no one would ever know, but Amy
continued into the crossroads without stopping. The driver of a large truck,
unable to stop in time, ran into our car.
Jane
was killed immediately.
I
was slightly injured. The most difficult thing that I’ve ever done was to call
the Whites to tell them about the accident and that Jane had died. Painful as
it was for me to lose a good friend, I knew that it was far worse for them to
lose a child.
When
Mr. and Mrs. White arrived at the hospital, they found their two daughters
sharing a room. Sarah had a few cuts on the head; Amy’s leg was broken. They
hugged us all and cried tears of sadness and of joy at seeing their daughters.
They wiped away the girls' tears and made a few jokes at Amy as she learned to
use her crutches(拐杖).
To
both of their daughters, and especially to Amy, over and over they simply said,
“We’re so glad that you’re alive.”
I
was astonished. No blame. No accusations.
Later,
I asked the Whites why they never talked about the fact that Amy was driving
and had run a stop sign.
Mrs.
White said, “Jane’s gone, and we miss her terribly. Nothing we say or do will
ever bring her back. But Amy has her whole life ahead of her. How can she lead
a full and happy life if she feels we blame her for her sister's death?”
They
were right. Amy graduated from the University of California and got married
several years ago. She works as a teacher of learning-disabled students. She’s
also a mother of two little girls of her own, the oldest named Jane.
