Growing up across the street from each other in Twin Falls, Idaho,
Lisa Fry and Paula Turner never doubted their friendship would last forever. But
after Fry married, moved to New York
City and had a baby, her letters to Turner suddenly
went unanswered. “Do you think I’ve somehow offended(冒犯)her?” Fry asked her husband.
Turner, meanwhile, had convinced(使信服)herself she was no longer important to Fry. “She’s got a family now,” she told
herself. “We’re just too different to be close like before. ”
Finally, Fry picked up the courage to call her old friend. At first, the
conversation was awkward, yet soon they both accepted that they missed
each other. A month later, they got together and quickly fell into their old
habit of laughing and sharing confidences.
“Thank goodness I finally took action,” Fry says. “We both realized we were as important
to each other as ever. ”
There are good reasons to treasure our friendships. Some years ago a
public-opinion research firm, Roper Starch Worldwide, asked 2007 people to
identify one or two things that said the most about themselves. Friends far
outranked homes, jobs, clothes and cars.
“A well-established friendship carries a long history of experience and
interaction that defines who we are and keeps us connected,” says Donald Pannen, executive officer of the Western Psychological
Association. “It is a heritage we should protect. ”
Ironically(具有讽刺意味)says Brant R. Burleson, professor of communication at Purdue University
in West Lafayette, Ind. “the better friends you are, the more
likely you’ll face conflicts. ” And the outcome can be exactly what you don’t
want--- an end to the friendship.
The good news is that most troubled friendships can be mended.
