     Slowly I climbed into the driver's seat of the old brown pontiac. "Hi, Miss Caroline!" cried the three

passengers, my friend Annie and her two children. No, I'm not Annie's driver. I'm just a friend.

     Let me explain. I'm 68, retired and live alone. Annie's 27, works as a part-time bank teller and is married

with two kids. We're different, but we have one very important need in common-a car. I couldn't afford to

fix my own car and the bus didn't go everywhere I needed to go.

     A friend had a suggestion. "My daughter Annie's been using my old pontiac while her husband job-hunts,"

he said, "He got laid off and I know they could use help with gas. Maybe you two could share the car."

     Share a car? We Americans are pretty territorial about our automobiles. Still, need overrode (压倒)

nervousness and I gave Annie a call. We quickly worked out a schedule. Three days a week for me, the rest

for her.

     Having wheels again was a huge help. Soon the car brought something more. Driving each other home

on the days we switched, Annie and I talked about everything.

     She had plenty of worries. Besides her finances, her dad's health was failing. However, she lifted my spirits!

She once said, "Life doesn't always turn out the way I want, but I trust things will work out. And they do.

Just like this car!"

     Annie and her family moved to Los Angeles. I still borrow the pontiac from her dad, who is healthy once

again. Now, whenever I drive the car, I think about Annie, and about how a simple exchange born of economic

need can become such a blessing. Like Annie says, life doesn't always turn out the way we want. But that

doesn't mean it doesn't turn out good.
